In at least UK populations, and perhaps others, SNP rs2187668 is a tag SNP for the HLA-DRB1*0301 allele. The HLA-DRB1*0301 allele is the allele presenting the highest risk for developing lupus, and it appears to act in a dominant manner (i.e. inheriting 2 copies is no worse than inheriting 1 copy). In dbSNP orientation, the risk allele is rs2187668(A), with an odds ratio of 2.3x (CI: 1.7 - 3.2, permuted p < 0.0001). From individuals with the most common rs2187668(G;G) genotype, risk is reduced for celiac disease, with an odds ratio of 0.30x according to a study of ~800 patients. rs2187668(A) also tags the tightly linked DQB1*0201 allele, which in turn is linked to DQA1*0501; together, these are known as the DQ2.5 haplotype. This is the most common haplotype associated with celiac diseas...

rs762551, also known as -164A>C or -163C>A, is a SNP encoding the CYP1A2*1F allele of the CYP1A2 gene. For historic reasons, the rs762551(C) allele is considered the wild-type, even though it is the rarer allele in most populations. The rs762551(A) allele is the 'fast metabolizer' allele known as CYP1A2*1F; the (C) allele is by comparison a slower metabolizer of certain substrates (including caffeine). In terms of genotypes, only rs762551(A;A) individuals are considered fast metabolizers. Individuals who are rs762551(A;C) heterozygotes or rs762551(C;C) homozygotes are both considered slow metabolizers. The CYP1A2 gene encodes a member of the cytochrome p450 family of proteins, which metabolize nutrients and drugs. One well known substrate of CYP1A2 is caffeine; individuals who are ca...

Substitution of the C allele with the risk allele T at a SNP in the first exon (rs2294008, which has r(2) = 0.995, D' = 0.999 with rs2976392) reduces transcriptional activity of an upstream fragment of the gene [OMIM:PROSTATE STEM CELL ANTIGEN; PSCA] [GWAS:Bladder cancer]

discussed in this blog post as possibly playing a role in coronary heart disease This SNP was also associated with increased risk for coronary artery disease in a Korean population. The association remained significant after adjusting for significant clinical covariates (P=0.001 to 0.024). We identified one risk haplotype (GGGG; P=0.017) and one protective haplotype (AAAA; P=0.007) for development of CAD. Further analysis suggested that the SNPs probably confer susceptibility to CAD in a dominance model (covariates-adjusted P=0.001 to 0.024; OR=2.37 to 1.54). Also found to be significant in a study of 416 Italian myocardial infarction patients. Found to be associated with coronary heart disease in a study of 1360 Chinese Han patients, with an odds ratio of 1.52 (CI: 1.13 - 2.04) for rs2383...

rs6983267 is a SNP on chromosome 8q24, associated with increased risk for several cancers, particularly prostate cancer. In studies dividing the 8q24 region, this SNP falls in region 3. In a study of over 3,600 Caucasians with prostate cancer, rs6983267 is one of five SNPs used (with family history as a sixth factor) to cumulatively predict overall risk. On their own, the rs6983267(G;G) and (G;T) risk genotypes yield an odds ratio for developing prostate cancer of 1.37 (CI: 1.18-1.59, p=3.4-10e-5) and may account for 22.2% of population attributable risk. The increased risk of developing prostate cancer associated with rs6983267 now appears to be independent of the risk associated with its close neighbor, rs1447295. The odds ratio for heterozygotes is estimated to be 1.26 (CI: 1.13 - 1.41)...

This SNP, in the ACTN3 gene, encodes a premature stop codon in a muscle protein called alpha-actinin-3. The polymorphism alters position 577 of the alpha-actinin-3 protein. In the (C;C) genotype is often called RR. The truncated (T;T) is often called XX. (T;T) is under-represented in elite strength athletes, consistent with previous reports indicating that alpha-actinin-3 deficiency appears to impair muscle performance. The most common nucleotide at this position, (C), encodes an arginine (amino acid code R), the alternative T allele encodes a stop codon (X). Hence, the SNP is referred to as R577X, with homozygotes being either RR or XX and heterozygotes being RX. XX individuals completely lack the expression of alpha-actinin-3. An earlier report studying a relatively small number of Austr...

rs3129934 is a SNP near the HLA-class II region that may be associated with several autoimmune diseases. In a study of two cohorts (Spanish and American multiple sclerosis patients, each numbering several hundred), rs3129934 was the SNP most associated with increased risk for multiple sclerosis. The odds ratio was 3.3 (CI: 2.3 - 4.9, p = 9 x 10e-11). Seven other SNPs were also identified in this study as associated with increased risk for MS. associated with type-1 diabetes 23andMe uses rs9273363 instead of rs3129934 in its reports on type 1 diabetes risk.

This SNP, rs10757278, is one of several clustered together in a region of chromosome 9 that has been linked to increased risk for heart disease and potentially diabetes. The overall estimate of heart disease cases that may involve this SNP (or related ones nearby) is said to be 20-30%. The risk allele, rs10757278(G), shows an increased association for myocardial infarctions ('MI'; heart attacks) both in general and more specifically in so-called early onset MI. The odds ratio relative to rs10757278(A:A) 'noncarrier' individuals for rs10757278(G;G) individuals is 1.64 (CI: 1.47-1.82), and for carriers of one risk allele, i.e. rs10757278(A;G) individuals, 1.26 (CI: 1.16-1.36). For early onset MI, the odds are slightly higher; homozygote rs10757278(G;G) individuals have an odds ratio of 2.02 ...

nature SNP rs1042725 is associated with height (P = 4E-8) in a study involving over 20,000 individuals. The gene harboring this SNP, HMGA2, is a strong biological candidate for having an influence on height, since rare, severe mutations in this gene are known to alter body size in mice and humans. rs1042725 is estimated to explain approx 0.3% of population variation in height in both adults and children (approx 0.4 cm increased adult height per C allele). rs1042725 is associated with increased height (0.36 cm 95% IC[0.12-0.61] per C allele, P=0.004). in men rs1042725 may explain 3% of height variability [PharmGKB:Non-Curated GWAS Results: A common variant of HMGA2 is associated with adult and childhood height in the general population (Initial Sample Size: 4,921 individuals; Replication S...

rs1051730, also known as D398N, is a SNP in the nicotinic acetylcholine receptor alpha 3 subunit CHRNA3 gene. In two recent (2008) studies, together comprising over 6,000 lung cancer patients of European ancestry, the rs1051730(T) allele was very significiantly associated with increased risk. Having one copy (i.e. being a rs1051730(C;T) genotype) increased risk for lung cancer about 1.3x, and having two copies (rs1051730(T;T) individuals) represented 1.8x increased risk. Up to 14% of lung cancer incidence may be attributable to this allele. An independent study published at the same time concluded that (T) allele carriers for SNP rs1051730 are not at higher risk of becoming smokers compared to (C) carriers. However, if they do smoke, (T) carriers are quite likely to smoke more cigarettes t...

SNPs in the SNAP25 gene were initially linked to intelligence but have failed to replicate . While now suspect, the original work can be found in . The (A;A) genotype averaged 2.84 PIQ points higher than the (A;G) genotype, which averages 2.8 PIQ points higher than the (G;G) genotype (p=0.0002). Variance in this SNP may account for 3.4% of the phenotypic variance in PIQ. rs363050 is in close linkage with rs353016, with r2 = 0.98, such that the rs363050(A) allele typically is linked to the rs353016(T) allele. For SNPs rs363039 - rs363043 - rs353016, respectively, the haplotype C-T-T is most associated with higher intelligence in children, whereas the haplotype C-C-T is most associated in adults (SNPs oriented as in dbSNP).

Also known as 'C/T(-13910)', and located in the MCM6 gene but with influence on the lactase LCT gene, rs4988235 is one of two SNPs that is associated with the primary haplotype associated with hypolactasia, more commonly known as lactose intolerance in European Caucasian populations. , In these populations, the rs4988235(T) allele is both the more common allele and the one associated with lactase persistence; individuals who are rs4988235(C;C) are likely to be lactose intolerant. In populations of sub-Saharan Africans, though, the rs4988235(T) allele is so rare that it's unlikely to be predictive of lactase persistence, and other SNPs are predictive instead. * See also OMIM 601806.0001 [PharmGKB:Curated Risk or phenotype-associated allele: C .Phenotype: The C allele of this SNP completely...

This SNP, located in an intron of the BTBD9 gene, has a variant that is seen somewhat more frequently in individuals with restless legs syndrome. The risk allele is rs3923809(A); carriers of two such alleles, i.e. those with rs3923809(A;A) genotypes, are estimated to be 1.9 fold more likely to have restless legs syndrome than rs3923809(G;G) individuals. The authors of this study suggest that perhaps half of the cases of restless legs syndrome may involve the rs3923809 risk genotypes. Consistent with this finding, another report about rs3923809 links the (G) minor allele to a lower frequency of restless legs syndrome with an overall odds ratio of 0.57 (CI: 0.48-0.68).

This study compared 608 patients of European ancestry with papillary thyroid cancer, which is the most common form of thyroid cancer and is highly treatable, to 901 healthy controls. The authors found an association between the SNP rs2910164, which is equivalent to the 23andMe SNP rs2961920, and risk for thyroid cancer. People with the AC genotype at rs2961920 had about 1.5 times the odds of papillary thyroid cancer compared to those with the AA genotype and about three times the odds compared to the CC genotype. Though this is an atypical risk pattern, the researchers speculate in a separate paper that having one copy of each form of the SNP increases production of molecules that regulate the cell's response to DNA damage, a process that is often involved in cancer.

rs4680 (Val158Met) is a well studied SNP in the COMT gene. spittoon summarizes them as *rs4680(A) = Met, more exploratory, lower enzymatic activity *rs4680(G) = Val, less exploratory, higher enzymatic activity Roughly speaking, the predominant wisdom (known colloquially as the warrior/worrier hypothesis) posits that people with Val alleles have increased COMT activity and lower prefrontal extracellular dopamine compared with those with the Met substitution. Val158 alleles may be associated with an advantage in the processing of aversive stimuli (warrior strategy), while Met158 alleles may be associated with an advantage in memory and attention tasks (worrier strategy).

If you are a 'taster', you're also likely to carry at least one rs10246939(C) and one rs1726866(C) allele since, along with rs713598(G), these three SNPs form the most common tasting haplotype. If you lack these alleles, you're quite likely (~80%) to be a non-taster of bitterness, meaning that foods that may taste bitter to others ta...

rs1801282, also known as Pro12Ala, is a common SNP in the peroxisome proliferator-activated receptor PPARG gene. The more common (C) allele (in dbSNP orientation) encodes the 'Pro' amino acid at this SNP position. rs1801282 has been reported to be associated with metabolic syndrome, but other studies have not been able to replicate any strong or significant effect. The association between type-1 diabetes and SNP rs1801282 is mentioned as being replicated in rs1801282 and risk of cognitive decline in elders? Maybe with diabetes. A ten-year study of 679 male patients with symptomatic coronary artery disease found that rs1801282(G) carriers had a much lower (10 year) cardiovascular risk, with the hazard ratio estimated to be 0.10 (CI: 0.01-0.70, p = 0.02) for ischemic heart disease and 0.24 f...

rs6457617 has been reported in a large study to be associated with rheumatoid arthritis. This SNP is reported to be the most statistically significant of many SNPs similarly located in the MHC region. The risk allele (oriented to the dbSNP entry) is (T); the odds ratio associated with heterozygotes is 2.36 (CI 1.97-2.84), and for homozygotes, 5.21 (CI 4.31-6.30). [GWAS:Rheumatoid arthritis]

rs872071 is a SNP associated with the interferon regulatory factor 4 IRF4 gene. In a GWAS study including over 1,500 Caucasian patients with chronic lymphocytic leukemia (CLL), the rs872071(G) allele showed the strongest association (p = 1.91 x 10e-20) of all SNPs studied. The reported odds ratio was 1.54.

The rs1799971(G) allele in exon 1 of the mu opiod receptor OPRM1 gene causes the normal amino acid at residue 40, asparagine (Asn), to be replaced by aspartic acid (Asp). In the literature this SNP is also known as A118G, N40D, or Asn40Asp. Carriers of at least one rs1799971(G) allele appear to have stronger cravings for alcohol than carriers of two rs1799971(A) alleles, and are thus hypothesized to be more at higher risk for alcoholism. However, subsequent research results are mixed, and there are other studies both agreeing or disagreeing with this finding Among 200+ alcoholics treated with naltrexone, rs1799971(G) carriers receiving the drug (even without behavioral intervention) had an increased percentage of days abstinent (p = .07) and a decreased percentage of heavy drinking days (p...

This SNP, located in an intron of the LOXL1 gene, was initially reported to be associated with exfoliation glaucoma. However, it was shown in the same study to no longer be significant once two other SNPs, which cause actual changes in the LOXL1 protein, were identified. More specifically, the risk allele rs2165241(T) was found to be associated with glaucoma only because it effectively predicted (with 90% probability) the actual high-risk haplotype consisting of rs1048661(G) and rs3825942(C), as oriented with respect to their entries in dbSNP. However, a meta-analysis published in 2010 concluded that it's likely that SNPs rs1048661 and rs2165241 are not directly implicated in the pathogenesis of glaucoma; only the nearby rs3825942 seemed to be the disease-associated SNP. rs2165241 was sign...

rs1800497, a SNP also known as the TaqIA (or Taq1A) polymorphism of the dopamine D2 receptor DRD2 gene (even though it is actually located over 10,000bp downstream of the gene), gives rise to the DRD2*A1 allele. This allele (rs1800497(T)) is associated with a reduced number of dopamine binding sites in the brain , and has been postulated to play a role in alcoholism, smoking, and certain neuropsychiatric disorders. The reduced number of dopamine binding sites may play a role in nicotine addiction by causing an 'understimulated' state that can be relieved by smoking (and/or use of other drugs).

rs601338 is found on chromosome 19 in the alpha(1,2)-fucosyltransferase FUT2 gene. The wild-type rs601338(G) encodes the 'secretor' (Se) allele, while rs601338(A) encodes the 'non-secretor' (se) allele. A study of 115 Swedish adults concluded that rs601338(A;A) homozygotes have genetic immunity to infection by the Norwalk norovirus, a major (and contagious) cause of acute gastroenteritis worldwide among adults. This illness is also known as 'cruise ship gastroenteritis.' Being a non-secretor may have other consequences, such as greater susceptibility to infection by influenza viruses and by some types of bacteria. 23andMe discusses these topics. In some non-Caucasian populations, a different SNP is responsible for non-secretor phenotypes. For example, although the Se allele is absent in Ja...

rs3754777 is a SNP in the serine threonine kinase 39 STK39 gene. A study of ~1,000 Amish originally identified rs3754777 and another SNP also in the STK39 gene, rs6749447, as being significantly associated with hypertension. This association was then found to also hold in patient data analyzed from the Framingham Heart Study and the Diabetes Genetics Initiative. On average, each minor allele, in this case rs3754777(A), is associated with 2.0 mmHg higher systolic blood pressure and a 1.0 mm Hg higher diastolic pressure.

rs2032583 is a SNP in the ABCB1 gene (also known as the MDR1 gene), which encodes a protein that transports certain molecules across the blood-brain barrier.

First discovered in 2004, rs34637584 is a SNP indicating a position within the LRRK2 that encodes a variant protein. This SNP is commonly referred to as the G2019S variant (or, mutation) based on the potential change from glycine (encoded by rs34637584(G) allele) to serine (encoded by the rs34637584(A) allele) at position 2019 of the LRRK2 protein. One copy of a rs34637584(A) allele is sufficient to greatly increase one's risk for Parkinson's disease. It is considered a disease causing mutation because it is rarely found in healthy, elderly people without Parkinson's disease, and it has been found in both familial and sporadic types of the disease. While there are many different SNPs that can influence one's risk for Parkinson's disease, rs34637584 is an especially common cause of the dise...

The SNP rs4804803 is a variant (-336A>G) in the promoter region for the CD209 gene that results in altered CD209 transcription. It is associated with modified resistance to several infectious diseases, including viruses (Hepatitis C, HIV, dengue, SARS), and bacteria (Mycobacterium tuberculosis), as well as other disorders of varying etiology (ulcerative colitis). The CD209 gene encodes a transmembrane receptor found on the surface of dendritic cells and macrophages. The protein product of CD209, DC-SIGN, plays an important role within both the innate and adaptive immune systems. DC-SIGN's role differs depending on which cell type it resides. On macrophages, DC-SIGN is responsible for recognizing and binding to mannose-type carbohydrates, which are found in almost all pathogenic organism...

rs671 is a classic SNP, well known in a sense through the phenomena known as the 'alcohol flush', also known as the 'Asian Flush' or 'Asian blush', in which certain individuals, often of Asian descent, have their face, neck and sometimes shoulders turn red after drinking alcohol. The rs671(A) allele of the ALDH2 gene is the culprit, in that it encodes a form of the aldehyde dehydrogenase 2 protein that is defective at metabolizing alcohol. This allele is known as the ALDH*2 form, and individuals possessing either one or two copies of it show alcohol-related sensitivity responses including facial flushing, and severe hangovers (and hence they are usually not regular drinkers). Perhaps not surprisingly they appear to suffer less from alcoholism and alcohol-related liver disease. Tests for th...

rs11887534, a SNP in the hepatic cholesterol transporter ABCG8 gene, has been implicated in gallstone disease, a process known formally as cholelithiasis. The common allele, rs11887534(G), encodes the aspartic acid (D), while the minor (C) allele encodes histidine (H). In a study of ~1,000 German patients, the overall odds ratio associated with rs11887534(C) carriers was 2.2 (CI: 1.8-2.6, p=1.4x10^-14), and for (C;C) homozygotes, 7x.

Also known as Arg389, variation at this SNP, located in the ADRB1 gene, may encode either the amino acid glycine or arginine at amino acid position 389 of the corresponding protein, the beta-1 adrenergic receptor (hence why it is frequently called Arg389Gly). This protein is the target of beta blocker drugs, and so how well the drug works to help lower a patients high blood pressure depends in part on this SNP. The status of this SNP is often reported together with the status of SNP rs1801252, which encodes an amino acid variant at position 49 of the same (ADRB1) protein. The rs1801253(G) allele encodes the glycine.

Apolipoprotein E ApoE status is technically defined by two different SNPs, rs429358 and rs7412. This SNP, rs4420638, is situated about 14kb away in the adjacent ApoC1 gene and is co-inherited with ApoE and thus associated with late-onset Alzheimer's disease. rs4420638 (the proxy SNP) is not independent of rs429358. These two SNPs are correlated with each other and it's believed that most of the association with AD at rs4420638 is due to its proximity to rs429358. That said, rs4420638 is not a perfect proxy for rs429358 either -- rs4420638 correlates better for certain genotypes and for certain ethnicities.

First discovered in 2004, rs34637584 is a SNP indicating a position within the LRRK2 that encodes a variant protein. This SNP is commonly referred to as the G2019S variant (or, mutation) based on the potential change from glycine (encoded by rs34637584(G) allele) to serine (encoded by the rs34637584(A) allele) at position 2019 of the LRRK2 protein. One copy of a rs34637584(A) allele is sufficient to greatly increase one's risk for Parkinson's disease. It is considered a disease causing mutation because it is rarely found in healthy, elderly people without Parkinson's disease, and it has been found in both familial and sporadic types of the disease.

rs1051730, also known as D398N, is a SNP in the nicotinic acetylcholine receptor alpha 3 subunit CHRNA3 gene. In two recent (2008) studies, together comprising over 6,000 lung cancer patients of European ancestry, the rs1051730(T) allele was very significiantly associated with increased risk. Having one copy (i.e. being a rs1051730(C;T) genotype) increased risk for lung cancer about 1.3x, and having two copies (rs1051730(T;T) individuals) represented 1.8x increased risk.

rs1800562 represents a SNP that accounts for ~85% of all cases of hemochromatosis, a disorder whose symptoms include cirrhosis of the liver, diabetes, hypermelanotic pigmentation of the skin, and heart failure. OMIM indicates that liver cancer is responsible for about one-third of deaths of rs1800562(A;A) homozygotes, and since hemochromatosis is a relatively easily treated disorder if diagnosed, this is a form of preventable cancer. The rs1800562(A) allele is known as the C282Y mutation, and it is found at a frequency of around 5-10% in many Caucasian populations, leading to an incidence of (A;A) homozygotes around 1 in 200. Early identification of rs1800562(A;A) homozygotes can prevent complications of hemochromatosis; however, the percentage of all (A;A) homozygotes who actually develop...

rs5030865 is a SNP in the CYP2D6 gene which defines two inactive variants, CYP2D6*8 and CYP2D6*14. This SNP has changed orientation in different reference genome builds and also has more than two allele changes possible, so references to it can be very confusing. The below are in genome build 37.1 plus orientation, while the 'also knowns' are in minus orientation: rs5030865(C) is the normal variant<br> rs5030865(A) is the CYP2D6*8 inactive variant, also known as 1758G>T or G169X<br> rs5030865(T) is the CYP2D6*14 inactive variant, also known as 1758G>A or G169R [OMIM:?]

rs1080983 is a SNP near the 5' end of the CYP2D6 gene. Little is known of the significance of either allele.

The wild type (normal) allele at this SNP is (G). The (A) variant indicates the presence of a non-wild type CYP2D6 variant, but it appears in many different variants so it can not be used to determine the presence of any particular variant. Inheriting a normal number of copies of this allele results in CYP2D6 function that is indistinguishable from wild-type (normal) activity. However, this variant has been seen present in higher copy numbers, and in these cases, can result in the ultrafast metabolizer phenotype . [PharmGKB:In-Depth Risk or phenotype-associated allele: T. Phenotype: The CYP2D6*2A haplotype was associated with lower incidence of breast cancer on tamoxifen compared to placebo in a prevention study. The CYP2D6*2A allele may be associated with increased efficacy of tamoxifen....

The (-) form of this SNP, representing a deletion of one nucleotide, causes a frameshift such that the resulting CYP2D6 protein is nonfunctional. The associated allele is also known as CYP2D6*6, and there are several subtypes but they are all nonfunctional. If two copies of this (or similar) changes are inherited, CYP2D6 poor metabolism ('PM') is observed. CYP2D6 poor metabolism may affect the efficacy or degree of side effects of drugs metabolized by CYP2D6, such as dextromorphan, sparteine, nortriptyline, venlafaxine and codeine. [PharmGKB:Curated This variant is part of the CYP2D6*6 PM haplotype. Plasma concentrations of metoprolol were shown to be were 4.9-fold higher in the PMs, with greater reductions in heart rate, diastolic blood pressure, and mean arterial pressure in PMs than in...

rs5030656, also known as 2615_2617delAAG or K281del, is a SNP in the CYP2D6 gene. The rs5030656(-) allele defines the CYP2D6*9 variant, which has decreased activity.

The wild type (normal) allele at this SNP is (C). The (T) variant indicates the presence of a non-wild type CYP2D6 variant, but it appears in many different variants so it can not be used to determine the presence of any particular variant. The most common variants it appears in are CYP2D6*10 and CYP2D6*4, but these are not the only ones. While this is the defining mutation for CYP2D6*10, it is not possible by itself for this mutation to determine a particular variant. In addition, the CYP2D6*4 variant includes this mutation, but the defining mutation 1846G>A SNP is not available in the common direct to consumer testing services. While it is not possible for this mutation to identify one particular variant, all the variants in which it appears have reduced or no CYP2D6 activity. If two ...

rs28371725, also known as 2988G>A, is a SNP in the CYP2D6 gene. The rs28371725(A) allele defines the CYP2D6*41 variant, which has decreased activity. 23andMe also has SNP i4001476 at the same position. [PharmGKB:In-Depth This variant is part of the CYP2D6*41 IM haplotype. Plasma concentrations of metoprolol were shown to be were 4.9-fold higher in the PMs, with greater reductions in heart rate, diastolic blood pressure, and mean arterial pressure in PMs than in non-PMs.]

The wild type allele for this SNP is (G) in minus orientation. When it changes to (C) it is known as 3877G>C and is a marker for non-functioning variant CYP2D6*4H. When it changes to (A) it is known as 3877G>A and is a marker for variant CYP2D6*52 which is possibly a decreased functioning variant, though more study is needed. Please note that this is in minus orientation and the 3877G>C version is subject to ambiguous flip.
