Summary
1PYGM-R50XHighWell-establishedWell-established pathogenic

Recessive, Carrier (Heterozygous)
0.00195204Causes Glycogen Storage Disease Type V (McArdle's disease) in a recessive manner.1
2CBS-I278THighLikelyLikely pathogenic

Recessive, Carrier (Heterozygous)
0.00288158This recessive mutation causes homocystinuria in a recessive manner and is found in patients responsive to pyridoxine treatment.1
3MATN3-T303MModerateUncertainUncertain pathogenic

Unknown, Heterozygous
0.0106698An Iceland study implicated this in causing increased osteoarthritis -- in particular, hand osteoarthritis. Because the variant is rare, the statistical significance of observations is weak. The authors estimate that individuals heterozygous for this variant have a 2.1-fold risk for hand osteoarthritis.1
4DRD2-S311CLowLikelyLikely pathogenic

Dominant, Heterozygous
0.0168247Various studies report this variant in a dopamine receptor is associated with increased risk for schizophrenia. Assuming an average 1% chance of schizophrenia in the general population, combined data suggests carriers of this variant have a risk of 1.4% (0.4% increased risk above average).1
5NOD2-R702WLowLikelyLikely pathogenic

Complex/Other, Heterozygous
0.0334821NOD2 encodes a protein involved in bacterial recognition. This variant is associated with Crohn's disease in European populations, but not in Korean or Japanese groups.1
6CETP-A390PLowLikelyLikely pathogenic

Unknown, Heterozygous
0.0388548This variant is associated with slightly lower HDL (good) cholesterol, although it has a negligible effect (around 2 mg/dl).1
7MTRR-I49MLowLikelyLikely pathogenic

Recessive, Carrier (Heterozygous)
0.451199This common variant (HapMap allele frequency of 31.3%) in a protein involved in folate (B9) and cobalamin (B12) metabolism and is often reported as "MTRR I22M" (an alternative transcript position). Mothers homozygous for this variant are associated with having around a increased chance of a child with Down syndrome (risk of 0.4%, average risk in population is 0.25%). Notably, age plays a far larger role in the rate of Down syndrome (risk is 4.5% for a mother 45-years-of-age), and it is unknown how this variant may combine with the effect of age. There are conflicting reports associating this variant with incidence of neural tube defects, possibly when combined with MTHFR A222V.1
8rs5186LowLikelyLikely pathogenic

Unknown, Heterozygous
0.214878This common noncoding genetic variant has an allele frequency of ~30% and is associated with an increased risk of hypertension. If ~25% of non-carriers have hypertension, Bonnardeaux et al's data predict ~4% increased risk of hypertension per copy of this variant. This SNP is in the 3' noncoding region of the AGTR1 transcript (angiotensin II type 1 receptor), also known as AT2R1 or AT1R, which is a target of hypertension drugs.1
9RNASEL-E265XLowUncertainUncertain pathogenic

Dominant, Heterozygous
0.00288158Implicated in causing familial prostate cancer, but later findings fail to confirm this. The variant is equally common in the control population, which strongly contradicts the original hypothesis of a high penetrance effect. If the variant has any effect on prostate cancer it seems likely to be low penetrance (any evidence for this is, however, very weak).1
10RNASEL-R462QLowUncertainUncertain pathogenic

Complex/Other, Heterozygous
0.278026Associated with increased risk of prostate cancer in individuals who already have a family history of prostate cancer, but studies have been unable to replicate this finding in sporadic (non-familial) prostate cancer cases.1
11TP53-P72RLowUncertainUncertain pathogenic

Unknown, Homozygous
0.627743This is a common variant was first reported as a polymorphism. It has since had mixed associations with cancer: Storey et al. conclude a 7x *increased* risk of HPV cancer for homozygotes vs hets, but Jones et al. find a 1.98x *decreased* risk for colorectal cancer. This variant may have significant impact on particular cancers, but it is unclear what effect it has on the overall burden of cancer.1
12H6PD-R453QLowUncertainUncertain pathogenic

Recessive, Carrier (Heterozygous)
0.308886This common variant may have a small pathogenic effect by contributing to cortisone reductase deficiency (a rare abnormality) when homozygous and combined with a serious pathogenic variant. The same authors have tested and ruled out a contribution to polycystic ovary syndrome (similar phenotype, more common disease).1
13SP110-L425SLowUncertainUncertain pathogenic

Unknown, Homozygous
0.863357This variant is associated with a slightly increased risk of tuberculosis. It is unclear whether it is itself causal, or in linkage disequilibrium with some other causal variant that has a stronger effect.1
14ERCC6-R1213GLowUncertainUncertain pathogenic

Recessive, Carrier (Heterozygous)
0.196877When homozygous, this variant may cause Cockayne Syndrome, which is a severe autosomal-recessive disorder characterized by abnormal early growth and development, abnormal sensitivity to sunlight, and premature aging. Cockayne Syndrome Type I and Type II lead to death in early childhood. Several other variants in the ERCC6 gene are linked to Cockayne Syndrome. This variant may also be linked to age-related macular degeneration like other ERCC6 variants, and has been linked to colorectal cancer in one study. 1
15WFS1-R611HLowUncertainUncertain not reviewed

Recessive, Carrier (Heterozygous)
0.400446This nonsynonymous SNP is associated with Wolfram Syndrome (known as DIDMOAD), which is characterized by early-onset non-autoimmune diabetes mellitus, diabetes insipidus, optic atrophy, and deafness) and to adult Type Two Diabetes Mellitus. The WFS1 gene maps to chromosome 4p16.3. The variant has been shown to be statistically associated with type II diabetes in six UK studies and one study of Ashkenazi Jews (Sandhu, M., et al., Minton et al.).1
16DPYD-M166VHighLikelyLikely pharmacogenetic

Unknown, Heterozygous
0.0778955Associated with DPYD deficiency and poor prognosis for chemotherapy w/ 5-flurorouracil. 1
17CYP2C9-R144CModerateWell-establishedWell-established pharmacogenetic

Unknown, Heterozygous
0.0970982This variant, also called CYP2C9*2, is a pharmacogenetic variant that modulates sensitivity for Warfarin (due to reduced metabolism). This variant is associated with Caucasians. The FDA has approved reduced recommended Warfarin dosage based on the presence of this variant.1
18rs1544410LowUncertainUncertain pharmacogenetic

Unknown, Heterozygous
0.351562rs1544410 is a Vitamin D Receptor (VDR) single nucleotide polymorphism. It is unlikely that it has functional significance because it is located in an intron (Liu et. al.), but it is in strong linkage disequilibrium with rs731236 (Dvornyk et al), which is located in an exon. 1
19ABCC6-R1268QLowUncertainUncertain pharmacogenetic

Unknown, Heterozygous
0.218907This common polymorphism appears to not have a significant phenotypic impact. A few studies report weak but significant associations with plasma lipids (in Inuits) and thalidomide toxicity.1
20FUT2-W154XModerateWell-establishedWell-established protective

Recessive, Carrier (Heterozygous)
0.490519This recessive protective variant confers resistance to norovirus (which causes stomach flu). 20% of Caucasians and Africans are homozygous for this variant and are "non-secretors": they do not express ABO blood type antigens in their saliva or mucosal surfaces. Most strains of norovirus bind to these antigens in the gut, and so this non-secretor status confers almost total resistantance to most types of norovirus. There are notable exceptions, some strains of norovirus bind a different target and are equally infectious for secretors and non-secretors.1
21NPC1-H215RLowLikelyLikely protective

Complex/Other, Heterozygous
0.295687This variant is associated with a reduced risk of obesity, with an additive effect of -0.084 BMI per allele (an average of 0.54 pounds less, per allele, in a 5'6" individual). 1
22IL7R-T244ILowLikelyLikely protective

Unknown, Heterozygous
0.210169The reference genome variant for this allele has been associated with a slight increased risk of multiple sclerosis. Thus, this variant can be treated as a "protective" variant -- carriers of this variant are slightly less likely to have MS. Because the disease is rare and the effect of this variant is not very strong, the absolute decreased risk for carriers of this variant is less than .05% (less than 1 in 2000).1
23KCNJ11-K23ELowLikelyLikely protective

Unknown, Heterozygous
0.738148This variant is associated with decreased risk of type 2 diabetes. It is unclear whether this variant has additive effects, or acts in a dominant or recessive manner. Assuming diabetes has a lifetime risk of 36%, we estimate a decreased risk of around 1-2% per copy of this variant.1
24MTR-D919GLowUncertainUncertain protective

Complex/Other, Heterozygous
0.217234This variant was weakly associated with a protective effect vs. colorectal cancer, but only in individuals with low alcohol consumption. 1
25IRS2-G1057DLowUncertainUncertain protective

Unknown, Heterozygous
0.232615a.k.a Gly1057Asp, insulin receptor substrate-2 IRS2. The rs1805097(G) allele is associated with the Gly, and the (A) allele with Asp. A longevity study concluded that rs1805097(A;A) individuals were about twice as likely to live over 85 y/o (odds ratio 2.03, CI:1.39-2.99, p = .0003). 1
26TYR-R402QLowWell-establishedWell-established benign

Complex/Other, Heterozygous
0.204964This is a frequent pigmentation polymorphism in Europeans that affects function of the Tyrosinase gene. It is associated with blue instead of green eyes and sun sensitivity. For the most part this variant is benign, but many individuals with ocular albinism (which affects only the eyes) carry this variant along with another more severe variant in the same gene.1
27ARSA-N350SLowWell-establishedWell-established benign

Unknown, Heterozygous
0.183199This common variant (HapMap 24.1% allele frequency) causes a loss of a glycosylation site (affecting the size of the protein when studied with gel electrophoresis) but does not affect enzyme activity or stability.1
28ADA-K80RLowLikelyLikely benign

Recessive, Carrier (Heterozygous)
0.0635806This variant has a 3.5% allele frequency in 1000 genomes data. Although OMIM links this to disease, the paper they reference uses in vitro data to conclude that this is a functionally neutral polymorphism.1
29MLH1-I219VLowUncertainUncertain benign

Dominant, Heterozygous
0.239822Computational evidence, functional assays, and case/control studies suggest this variant is probably benign.1
30GUCY2D-A52SLowUncertainUncertain benign

Recessive, Homozygous
0.21016One publication suggested that this variant possibly causes Leber's congenital amaurosis in a recessive manner, but the frequency data (36% in 1000 genomes) contradicts any significant pathogenic effect.1
31KEL-T193MLowUncertainUncertain benign

Dominant, Heterozygous
0.0320692This variant is also known as Kell or K1 or K (capitalized) in the Kell antigen system. K1-negative mothers (carrying no copies of this variant) carrying K1-positive fetuses (heterozygous or homozygous) are at risk for hemolytic disease of the newborn. About 9% of caucasians carry one or two copies of K1.1
32LOXL1-R141LLowUncertainUncertain benign

Complex/Other, Heterozygous
0.255899Associated with exfoliative glaucoma & syndrome (XFG & XFS) in various populations, but with contradicting results (protective in Caucasians, pathogenic in Japanese). Based on this it seems the variation itself -- although it affects protein structure -- is not itself causing disease. Instead it is likely associated with other nearby causal variants. As such, it is evaluated as benign by GET-Evidence (which focuses on reporting causal variants). See detailed variant report for disease risk associations.1
33GJB3-R32WLowUncertainUncertain benign

Unknown, Heterozygous
0.022309Probably benign. Although Polyphen 2 predicts it be damaging and some publications suggested it might have a functional effect, others report it to be a fairly common polymorphism and functional studies failed to find a difference between it and wild type.1
34ELN-G581RLowUncertainUncertain benign

Unknown, Heterozygous
0.072876Probably a benign SNP, not rare (4.8% allele frequency in GET-Evidence data).1
35APOB-Y1422CLowUncertainUncertain benign

Unknown, Homozygous
0.999628This position is almost certainly an error in the HG18 reference sequence. 1
36DSPP-R68WLowUncertainUncertain benign

Unknown, Heterozygous
0.143045Probably benign. One report linked this to causing dentinogenesis Imperfecta type II in a large Swedish family, but subsequent publications have observed this is a common variant and conclude it is a nonpathogenic polymorphism.1
37MUSK-T100MLowUncertainUncertain benign

Unknown, Heterozygous
0.023413Probably benign.1
38RP1-N985YLowUncertainUncertain benign

Unknown, Heterozygous
0.348671Probably benign. One report linked this variant to high triglycerides, but a later paper found a nearby SNP with similar association and suggests that both findings are caused by linkage to an undiscovered causal variant.1
39PCSK9-G670ELowUncertainUncertain benign

Unknown, Homozygous
0.888269This variant is likely benign. 1
40SLC45A2-L374FLowUncertainUncertain benign

Unknown, Homozygous
0.691764Pigmentation allele for non-black hair, and consequently, possible increased susceptibility to malignant melanoma.1
41TAS2R38-I296VLowUncertainUncertain benign

Unknown, Heterozygous
0.463376This variant is associated with "taster" status of PTC, along with 49P and 262A. Due to linkage disequilibrium, the independent effects of positions 296 and 262 is unclear. The presence of 49P confers taster status in a dominant fashion, but in the absence of 49P, the presence of 262A/296V is still positively associated with tasting PTC.1
42TAS2R38-A49PLowUncertainUncertain benign

Unknown, Heterozygous
0.431121This variant is strongly associated with causing the "taster" phenotype of phenylthiocarbamine (PTC) in a dominant manner.1
43TYR-S192YLowUncertainUncertain benign

Unknown, Heterozygous
0.270682This variant is reported to affect skin pigmentation. It is associated with lighter skin in South Asians (OR 4-5) and with a lack of freckles in Europeans (OR 1.3).1
