Summary
1WNT10A-F228IModerateWell-establishedWell-established pathogenic

Unknown, Heterozygous
0.0187907Causes ectodermal dysplasia in a recessive manner (malformations of teeth and nails, abnormal/loss of sweating). Although reports have high statistical significance, allele frequency for this variant is high relative to the incidence of the disease. This suggests it may be milder than other pathogenic variants and cause disease with less than 100% penetrance and/or that the disease is more common than reported. Bohring et al. report heterozygotes for pathogenic variants in this gene often have milder skin, tooth, and nail abnormalities, with males having a higher rate of tooth abnormalities.1
2PPARG-P12AModerateUncertainUncertain not reviewed

Unknown, Heterozygous
0.08867821
3AMPD1-Q12XLowLikelyLikely pathogenic

Recessive, Carrier (Heterozygous)
0.0930643Causes Adenosine Deaminase Deficiency in a recessive manner. Most of the time individuals do not report symptoms, but when symptoms do exist they to be post-exercise symptoms of muscle weakness, muscle pain, and getting tired more quickly.1
4MBL2-R52CLowLikelyLikely pathogenic

Recessive, Carrier (Heterozygous)
0.048615This 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 D. See G54D (variant B) and G57E (variant C).1
5TLR5-R392XLowUncertainUncertain pathogenic

Complex/Other, Heterozygous
0.0439673This variant is believed to impair the ability to generate an immune response to the flagella of the bacteria. It is weakly associated with an increased incidence of Legionnaires' Disease, p = 0.085, increased lifetime risk of disease ~0.88% (about twice average). The variant is also weakly associated with a reduced incidence of systemic lupus erythematosus, p = 0.165.1
6TGFB1-R25PLowUncertainUncertain pathogenic

Complex/Other, Homozygous
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
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
8TP53-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
9WFS1-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
10CPN1-G178DLowUncertainUncertain pathogenic

Recessive, Carrier (Heterozygous)
0.0356014This rare variant (around 1% allele frequency) is hypothesized to cause carboxypeptidase N deficiency in a recessive manner, especially if combined with a more severe variant. However the findings lack statistical sigificance: only a single case study of an affected individual links this variant to causing the disease. There aren’t any follow-up in vitro studies testing whether this variant affects protein function.1
11rs1544410LowUncertainUncertain 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
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, Homozygous
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
14PRNP-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
15KCNJ11-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
16BRCA2-T1915MLowUncertainUncertain protective

Unknown, Heterozygous
0.0205429Serrano-Fernández et al. found this variant to be associated with a modest (OR = 1.61) but significant (P = 0.0007) reduction in breast cancer risk. 1
17ARSA-N350SLowWell-establishedWell-established benign

Unknown, Heterozygous
0.183199This common variant (HapMap 24.1% allele frequency) causes a loss of a glycosylation site (affecting the size of the protein when studied with gel electrophoresis) but does not affect enzyme activity or stability.1
18ADA-K80RLowLikelyLikely benign

Recessive, Homozygous
0.0635806This variant has a 3.5% allele frequency in 1000 genomes data. Although OMIM links this to disease, the paper they reference uses in vitro data to conclude that this is a functionally neutral polymorphism.1
19HTRA2-A141SLowLikelyLikely benign

Unknown, Heterozygous
0.016814Probably benign. One report proposed an association with increased risk for Parkinson's disease, but had very weak statistical significance. A later study found an equal incidence of this variant in cases and controls, contradicting any association with the disease.1
20SLC45A2-E272KLowLikelyLikely benign

Unknown, Heterozygous
0.0290946Pigmentation allele for black hair in Caucasian population.1
21PMS2-P470SLowLikelyLikely benign

Unknown, Heterozygous
0.374884Benign, common variant.1
22MLH1-I219VLowUncertainUncertain benign

Dominant, Heterozygous
0.239822Computational evidence, functional assays, and case/control studies suggest this variant is probably benign.1
23GUCY2D-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
24LOXL1-R141LLowUncertainUncertain benign

Complex/Other, Heterozygous
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
25TYR-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

Unknown, Heterozygous
0.0333767Reported as a nonpathogenic polymorphism.1
27PCCA-I475VLowUncertainUncertain benign

Unknown, Heterozygous
0.0377394Reported as a polymorphism, tentatively presumed benign.1
28AMPD1-P48LLowUncertainUncertain benign

Unknown, Heterozygous
0.0940695Probably benign, ancestral to15173240 pathogenic Q12X mutation.1
29APOB-Y1422CLowUncertainUncertain benign

Unknown, Homozygous
0.999628This position is almost certainly an error in the HG18 reference sequence. 1
30TPCN2-G734ELowUncertainUncertain benign

0.155549Probably benign.1
32ABCC11-G180RLowUncertainUncertain benign

Unknown, Heterozygous
0.0976947This variant is associated with dry type ear wax (a benign trait) in a recessive manner.1
33SLC45A2-L374FLowUncertainUncertain benign

Unknown, Heterozygous
0.691764Pigmentation allele for non-black hair, and consequently, possible increased susceptibility to malignant melanoma.1
34PKP2-L366PLowUncertainUncertain benign

Unknown, Heterozygous
0.221231This variant is a benign polymorphism. 1
35SPTA1-A970DLowUncertainUncertain benign

Unknown, Heterozygous
0.0373134This variant, also called alpha-IIa, has been seen frequently in individuals with recessive Hereditary spherocytosis. This appears to be the result of linkage to alpha-LEPRA (a C>T substitution at position -99 of intron 30); A970D is later reported as functionally neutral.1
36PCSK9-G670ELowUncertainUncertain benign

Unknown, Homozygous
0.888269This variant is likely benign. 1
37TAS2R38-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
38PTCH1-P1315LLowUncertainUncertain benign
