Summary
1THBD-A43THighUncertainUncertain pathogenic

Dominant, Heterozygous
0.00383583Reported to cause familial hemolytic-uremic syndrome in a dominant manner, a potentially lethal illness in children. If true, penetrance is not 100%, but some family history of the illness might be expected.1
2C3-R102GModerateLikelyLikely pathogenic

Complex/Other, Heterozygous
0.152073This variant (also called C3F) is common in Europeans (10.2% allele frequency), and is associated with age-related macular degeneration. In the US, 1.5% of adults over 40 have the disease, but the incidence increases strongly with age (>15% in women over 80). Assuming an average lifetime risk of ~10%, heterozygous individuals have a ~13% risk and homozygous have ~20%.1
3MEFV-E148QModerateUncertainUncertain pathogenic

Recessive, Carrier (Heterozygous)
0.0120929Some reports believe this cause Familial Mediterranean Fever in a recessive manner with reduced penetrance (i.e. not all get the disease). However, these reports lack strong statistical significance; other studies argue the variant is not associated with the disease.1
4CFTR-S1235RModerateUncertainUncertain pathogenic

Recessive, Carrier (Heterozygous)
0.00529838Reported to cause mild dysfunction of the cystic fibrosis gene, it may result in cystic fibrosis when combined with more severe variants.1
5PPARG-P12AModerateUncertainUncertain not reviewed

Unknown, Heterozygous
0.08867821
6MTRR-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
7RNASEL-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
8SP110-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
9H6PD-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
10TP53-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
11BRCA2-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
12MEFV-P369SLowUncertainUncertain pathogenic

Recessive, Carrier (Heterozygous)
0.00511247Weak evidence associating this with familial mediterranean fever, but there is a fairly high frequency of this allele. This variant might cause increased susceptibility to the disease but there is not enough evidence to be significant.1
13WFS1-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
14CLEC7A-Y238XLowUncertainUncertain pathogenic

Recessive, Carrier (Heterozygous)
0.0632088This variant has been found to impair homan mucosal antifungal defense and was implicated in vulvovaginal candidiasis and mucocutaneous infections in a Dutch family.1
15ITPA-P32TLowWell-establishedWell-established pharmacogenetic

Recessive, Carrier (Heterozygous)
0.0609779This variant is associated with inosine triphosphate pyrophosphohydrolase deficiency and may be associated with an adverse reaction to thiopurine drugs (which are used as immunosuppressants). Homozygotes have no detectable ITPase activity, individuals compound heterozygous with another less severe mutation also have severely reduced enzyme activity.1
16rs1544410LowUncertainUncertain 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
17ABCC6-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
18FUT2-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
19PRNP-M129VLowWell-establishedWell-established protective

Complex/Other, Homozygous
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
20NPC1-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
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, Homozygous
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
23LPL-S474XLowUncertainUncertain protective

Unknown, Heterozygous
0.0844953This variant actually increases LPL enzyme activity despite creating a termination codon (see Rip J et al). It appears to be a protective variant, associated with lower triglyceride levels--although the effect is quite weak and explains only 0.5-1% of triglyceride variation.1
24PMS2-P470SLowLikelyLikely benign

Unknown, Heterozygous
0.374884Benign, common variant.1
25GUCY2D-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
26RPGRIP1-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
27PCSK9-G670ELowUncertainUncertain benign

Unknown, Homozygous
0.888269This variant is likely benign. 1
28PCCA-I475VLowUncertainUncertain benign

Unknown, Heterozygous
0.0377394Reported as a polymorphism, tentatively presumed benign.1
29VWF-G2705RLowUncertainUncertain benign

Unknown, Heterozygous
0.0460123Probably benign, seems to be considered an uncommon polymorphism.1
30ABCC11-G180RLowUncertainUncertain benign

Unknown, Heterozygous
0.0976947This variant is associated with dry type ear wax (a benign trait) in a recessive manner.1
31SLC45A2-L374FLowUncertainUncertain benign

Unknown, Heterozygous
0.691764Pigmentation allele for non-black hair, and consequently, possible increased susceptibility to malignant melanoma.1
32TAS2R38-A49PLowUncertainUncertain benign

Unknown, Heterozygous
0.431121This variant is strongly associated with causing the "taster" phenotype of phenylthiocarbamine (PTC) in a dominant manner.1
33TAS2R38-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
34APOB-Y1422CLowUncertainUncertain benign

Unknown, Homozygous
0.999628This position is almost certainly an error in the HG18 reference sequence. 1
35TYR-S192YLowUncertainUncertain benign

Unknown, Homozygous
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
