Summary
1PRPH-D141YHighUncertainUncertain pathogenic

Recessive, Carrier (Heterozygous)
0.00365206Hypothesized to cause ALS (or increased susceptibility) in a recessive manner, but this is based on a single observation and may lack statistical significance. The mutant protein appears to form abnormal aggregates.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
4MTRR-I49MLowLikelyLikely pathogenic

Recessive, Homozygous
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
5MBL2-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
6WFS1-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
7TGFB1-R25PLowUncertainUncertain pathogenic

Complex/Other, Heterozygous
0.0488858This variant in a growth factor gene is associated with variation in TGFB1 levels; this has been associated with various pathogenic and some protective effects, including: more hepatic fibrosis progression in hep C patients, lower risk of cleft palate, anticorrelation with longevity, higher risk of myocardial infarction and lower risk of hypertension.1
8RNASEL-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
9SP110-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
10TP53-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
11CYP2C9-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
12ABCC6-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
13FUT2-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
14NPC1-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
15CFH-V62ILowLikelyLikely protective

Complex/Other, Heterozygous
0.391616Associated with a decreased risk for age related macular degeneration (ARMD). Homozygotes for this have a 4-5% decreased attributable risk (3-4% vs. average 8% risk), heterozygotes have slightly lower than average risk (7%). Non-carriers have an increased risk (12-13%). ARMD impairs sharp vision as age progresses. While there is no cure, treatment can slow progression of the disease and environmental factors (smoking and obesity) contribute to higher risk.1
16KCNJ11-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
17IL7R-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
18MTR-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
19TYR-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
20PMS2-P470SLowLikelyLikely benign

Unknown, Homozygous
0.374884Benign, common variant.1
21LOXL1-R141LLowUncertainUncertain benign

Complex/Other, Homozygous
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
22RPGRIP1-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
23PCSK9-G670ELowUncertainUncertain benign

Unknown, Homozygous
0.888269This variant is likely benign. 1
24ABCC11-G180RLowUncertainUncertain benign

Unknown, Heterozygous
0.0976947This variant is associated with dry type ear wax (a benign trait) in a recessive manner.1
25APOB-Y1422CLowUncertainUncertain benign

Unknown, Homozygous
0.999628This position is almost certainly an error in the HG18 reference sequence. 1
26TPCN2-G734ELowUncertainUncertain benign

Unknown, Heterozygous
0.286166Pigmentation allele.1
27PKP2-L366PLowUncertainUncertain benign

Unknown, Heterozygous
0.221231This variant is a benign polymorphism. 1
28SLC45A2-L374FLowUncertainUncertain benign

Unknown, Homozygous
0.691764Pigmentation allele for non-black hair, and consequently, possible increased susceptibility to malignant melanoma.1
29RP1-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
30PTCH1-P1315LLowUncertainUncertain benign

Unknown, Heterozygous
0.29631Common polymorphism, presumed benign.1
31MUSK-T100MLowUncertainUncertain benign
