Summary
1PPARG-P12AModerateUncertainUncertain not reviewed

Unknown, Heterozygous
0.08867821
2COL4A1-Q1334HLowLikelyLikely pathogenic

Dominant, Heterozygous
0.324689This common variant has been associated with arterial stiffness and, in Japanese, a small increased risk of myocardial infarction (MI, a.k.a. heart attack). This last observation supported a dominant effect for this variant and, assuming a lifetime risk of 15% for MI, we estimate carriers have an additional risk of 0.5-3%.1
3MTRR-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
4WFS1-R611HLowUncertainUncertain not reviewed

Recessive, Homozygous
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
5LRP5-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
6RNASEL-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
7ELAC2-S217LLowUncertainUncertain pathogenic

Complex/Other, Homozygous
0.273471Reported to be associated with increased susceptibility to prostate cancer, but later studies weaken the hypothesis. Xu et al.'s meta-analysis concludes that there is a small but significant increased risk (OR = 1.13). Assuming a lifetime risk of 16% for prostate cancer we calculate this leads to an increased risk of ~1.5% (17.5% total).1
8SP110-L425SLowUncertainUncertain pathogenic

Unknown, Heterozygous
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
9TP53-P72RLowUncertainUncertain pathogenic

Unknown, Heterozygous
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
10rs1544410LowUncertainUncertain pharmacogenetic

Unknown, Homozygous
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
11FUT2-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
12NPC1-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
13ABCG5-R50CLowLikelyLikely protective

Unknown, Heterozygous
0.0684142This variant has a mild protective effect on blood cholesterol. It is associated with slightly lower total and LDL cholesterol levels.1
14IL7R-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
15MTR-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
16TYR-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
17RPGRIP1-A547SLowUncertainUncertain benign

Complex/Other, Homozygous
0.232202Probably benign. Implicated in causing autosomal recessive cone-rod dystrophy, but a later report found the same incidence in controls and concludes it is not causal.1
18TPCN2-G734ELowUncertainUncertain benign

Unknown, Heterozygous
0.286166Pigmentation allele.1
19PTCH1-P1315LLowUncertainUncertain benign

Unknown, Heterozygous
0.29631Common polymorphism, presumed benign.1
20PCSK9-G670ELowUncertainUncertain benign

Unknown, Homozygous
0.888269This variant is likely benign. 1
21PKP2-L366PLowUncertainUncertain benign

Unknown, Homozygous
0.221231This variant is a benign polymorphism. 1
22APOB-Y1422CLowUncertainUncertain benign

Unknown, Homozygous
0.999628This position is almost certainly an error in the HG18 reference sequence. 1
23RP1-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
24SLC45A2-L374FLowUncertainUncertain benign

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