Summary
1MATN3-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
2PIGR-A580VLowLikelyLikely pathogenic

Complex/Other, Heterozygous
0.247537In a Japanese study, this variant was associated with an increased risk for immunoglobulin A nephropathy (IgAN), a rare disease. The chances of having this disease, even with this variant, is less than 0.1%.1
3rs5186LowLikelyLikely 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
4KRT5-G138ELowLikelyLikely pathogenic

Unknown, Heterozygous
0.0521472This variant is associated with 1.25x increased risk of basal cell carcinoma (common skin cancer, rarely malignant).1
5MTRR-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
6LRP5-A1330VLowUncertainUncertain pathogenic

Complex/Other, Heterozygous
0.110367In a study of a UK population this variant was associated with a small increased risk of osteoporosis and osteoporotic bone fractures, with each copy of the variant presumed to have an additive effect. A study in Chinese young men failed to find an association with peak bone density. 1
7SP110-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
8WFS1-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
9BRCA2-N372HLowUncertainUncertain pathogenic

Recessive, Carrier (Heterozygous)
0.23656This is a common variant of BRCA2 (HapMap allele frequency of 23%). The variant is weakly associated with an increased chance of breast cancer, and zygosity of the variant is associated with sex of children: male children are more likely to be homozygous for this variant, female children are more likely to be heterozygous.1
10HFE-H63DLowUncertainUncertain pathogenic

Recessive, Carrier (Heterozygous)
0.109965There have been some hypotheses that this variant contributes to causing hereditary hemochromatosis, possibly as a compound heterozygote, but some others treat it as a polymorphism. Cys282Tyr is the classic causal variant and itself has very low penetrance. Mouse studies indicates this variant has a similar but weaker effect; if it has any effect at all its penetrance may be quite low and/or require modifier alleles.1
11ABCC6-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
12rs1544410LowUncertainUncertain 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
13PRNP-M129VLowWell-establishedWell-established protective

Complex/Other, Heterozygous
0.339561This variant is associated with some protective effects for prion disease -- individuals homozygous for this variant are less susceptible to Creutzfeldt-Jakob, and Papua New Guinea individuals heterozygotes at this site are less susceptible to kuru. 1
14KCNJ11-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
15SLC45A2-E272KLowLikelyLikely benign

Unknown, Heterozygous
0.0290946Pigmentation allele for black hair in Caucasian population.1
16TAS2R38-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
17TYR-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
18TPCN2-G734ELowUncertainUncertain benign

Unknown, Heterozygous
0.286166Pigmentation allele.1
19TAS2R38-A49PLowUncertainUncertain benign

Unknown, Heterozygous
0.431121This variant is strongly associated with causing the "taster" phenotype of phenylthiocarbamine (PTC) in a dominant manner.1
20PCSK9-G670ELowUncertainUncertain benign

Unknown, Homozygous
0.888269This variant is likely benign. 1
21FMO3-V257MLowUncertainUncertain benign

Unknown, Heterozygous
0.0570738This common variant (HapMap allele frequency of 9.2%) appears to have no functional effect. OMIM has recorded it as having been seen homozygously in an individual with Trimethylaminuria, but Treacy et al. 1998 conclude it is a polymorphism.1
22DSPP-R68WLowUncertainUncertain benign

Unknown, Homozygous
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
23APOB-Y1422CLowUncertainUncertain benign

Unknown, Homozygous
0.999628This position is almost certainly an error in the HG18 reference sequence. 1
24HR-T1022ALowUncertainUncertain benign

Recessive, Carrier (Heterozygous)
0.0969511Probably benign. One study implicated it in causing alopecia universalis, but a later report noted the variant has an allele frequency inconsistent with the rarity of that disease.1
25KRT85-R78HLowUncertainUncertain benign

Recessive, Carrier (Heterozygous)
0.042466Presumed benign. Although this variant was implicated in causing ectodermal dysplasia in a recessive manner in two Pakistani families (one of which was large and consanguineous), GET-Evidence reports that the variant has been seen in 5 out of 114 random control chromosomes. This strongly contradicts a severe pathogenic effect.1
26RP1-N985YLowUncertainUncertain benign

Unknown, Homozygous
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
27MAPT-R370WLowUncertainUncertain benign

Unknown, Heterozygous
0.155549Probably benign.1
28SLC45A2-L374FLowUncertainUncertain benign

Unknown, Heterozygous
0.691764Pigmentation allele for non-black hair, and consequently, possible increased susceptibility to malignant melanoma.1
