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
3MBL2-G54DLowLikelyLikely pathogenic

Recessive, Carrier (Heterozygous)
0.103923This variant is associated with mannose binding protein deficiency which leads to impaired complement system immune response to mannose-rich pathogens. Patients homozygous for this allele or compound heterozygous are likely to have increased susceptibility to infection, but Hellemann et al. report heterosis for intensive care outcomes in heterozygous subjects. The wild-type version of this gene is known as variant allele A, while this is called variant allele B. See R52C (variant D) and G57E (variant C).1
4MTRR-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
5APOA5-S19WLowLikelyLikely pathogenic

Unknown, Homozygous
0.0646151This variant, also known as APOA5*3, is associated with higher plasma triglyceride concentrations but no significant correlation with coronary artery disease itself has been found.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
7POLG-Q1236HLowUncertainUncertain pathogenic

Complex/Other, Heterozygous
0.0581893Generally a nonpathogenic polymorphism, but may have a modifier effect that increases severity when combined in cis with other pathogenic variants.1
8ELAC2-S217LLowUncertainUncertain pathogenic

Complex/Other, Heterozygous
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
9HFE-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
10SP110-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
11H6PD-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
12WFS1-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
13DPYD-M166VHighLikelyLikely pharmacogenetic

Unknown, Heterozygous
0.0778955Associated with DPYD deficiency and poor prognosis for chemotherapy w/ 5-flurorouracil. 1
14CYP2C9-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
15rs1544410LowUncertainUncertain 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
16ABCC6-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
17FUT2-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
18CASP10-V410ILowLikelyLikely protective

Dominant, Heterozygous
0.0474066Reported to have a protective effect on breast cancer. If the lifetime risk of breast cancer is 12%, women with this variant may have a lower risk of 8-9% (30% less than average).1
19NPC1-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
20ABCG5-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
21IL7R-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
22KCNJ11-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
23TYR-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
24PMS2-P470SLowLikelyLikely benign

Unknown, Heterozygous
0.374884Benign, common variant.1
25OCA2-R305WLowLikelyLikely benign

Unknown, Heterozygous
0.0815207This variant is associated with eye color, as is OCA2 Arg419Gln. Individuals with this variant are more likely to have brown/black eyes (as opposed to blue/gray or green/hazel). Other variants in this gene are associated with oculocutaneous albinism (albinism which involves skin and eyes).1
26FBN2-S2580LLowUncertainUncertain benign

Dominant, Heterozygous
0.0779885Probably benign -- initially associated with congenital contractual arachnodactyly, but later reports classify it as a nonpathogenic polymorphism.1
27MLH1-I219VLowUncertainUncertain benign

Dominant, Heterozygous
0.239822Computational evidence, functional assays, and case/control studies suggest this variant is probably benign.1
28KEL-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
29RPGRIP1-A547SLowUncertainUncertain benign

Complex/Other, Heterozygous
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
30FANCA-S1088FLowUncertainUncertain benign

Unknown, Heterozygous
0.0584681Probably benign. One report hypothesized this variant causing Fanconi Anemia, but the allele frequency (3-7%) is high enough to contradict a highly penetrant pathogenic effect. Later authors have concluded this is a polymorphism, not pathogenic.1
31F5-M413TLowUncertainUncertain benign

Unknown, Heterozygous
0.0580963Presumed benign. This variant is not particularly rare and has not been reported to cause disease.1
32APOB-Y1422CLowUncertainUncertain benign

Unknown, Homozygous
0.999628This position is almost certainly an error in the HG18 reference sequence. 1
33CYP27A1-P384LLowUncertainUncertain benign

Unknown, Heterozygous
0.0177542Probably not pathogenic. Although predicted to be disruptive and treated by some as pathogenic, reports of this variant in cases were all linked with an upstream frameshift variant -- this supports the variant as a nonpathogenic ancestral polymorphism.1
34TYR-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
35SLC45A2-L374FLowUncertainUncertain benign

Unknown, Homozygous
0.691764Pigmentation allele for non-black hair, and consequently, possible increased susceptibility to malignant melanoma.1
36PTCH1-P1315LLowUncertainUncertain benign

Unknown, Heterozygous
0.29631Common polymorphism, presumed benign.1
37PCSK9-G670ELowUncertainUncertain benign

Unknown, Homozygous
0.888269This variant is likely benign. 1

Unknown, Homozygous
0.155549Probably benign.1
39RP1-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
