Summary
1CFTR-G576AHighLikelyLikely pathogenic

Recessive, Carrier (Heterozygous)
0.00474684Associated with causing congenital bilateral absence of the vas deferens in a recessive manner. Reported cases were compound heterozygous with CFTR-F508Del.1
2MBL2-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
3WFS1-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
4BRCA2-N372HLowUncertainUncertain pathogenic

Recessive, Homozygous
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
5RNASEL-R462QLowUncertainUncertain pathogenic

Complex/Other, Homozygous
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
6LRP5-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
7TP53-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
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
9rs1544410LowUncertainUncertain 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
10NPC1-H215RLowLikelyLikely protective

Complex/Other, Homozygous
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
11KCNJ11-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
12ABCG5-R50CLowLikelyLikely protective

Unknown, Homozygous
0.0684142This variant has a mild protective effect on blood cholesterol. It is associated with slightly lower total and LDL cholesterol levels.1
13LIG4-A3VLowUncertainUncertain protective

Dominant, Heterozygous
0.035843One report has associated this with a decreased risk of multiple myeloma.1
14LPL-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
15EFHC1-R182HLowLikelyLikely benign

Unknown, Homozygous
0.0439673Probably benign. OMIM appears to incorrectly interpret literature as linking this variant to juvenile myoclonic epilepsy; the authors report it as a polymorphism.1
16MLH1-I219VLowUncertainUncertain benign

Dominant, Heterozygous
0.239822Computational evidence, functional assays, and case/control studies suggest this variant is probably benign.1
17GUCY2D-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
18RPGRIP1-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
19LOXL1-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
20TYR-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
21PCCA-I475VLowUncertainUncertain benign

Unknown, Heterozygous
0.0377394Reported as a polymorphism, tentatively presumed benign.1
22PHYH-P29SLowUncertainUncertain benign

Unknown, Heterozygous
0.155326Probably benign. This variant was implicated as causing Refsum Disease in a recessive manner, but a subsequent publication noted that all instances were linked with other explanatory mutations. The high allele frequency of this variant in the population (7-13%) contradicts a pathogenic hypothesis.1
23KRT85-R78HLowUncertainUncertain benign

Recessive, Carrier (Heterozygous)
0.042466Presumed benign. Although this variant was implicated in causing ectodermal dysplasia in a recessive manner in two Pakistani families (one of which was large and consanguineous), GET-Evidence reports that the variant has been seen in 5 out of 114 random control chromosomes. This strongly contradicts a severe pathogenic effect.1
24APOB-Y1422CLowUncertainUncertain benign

Unknown, Homozygous
0.999628This position is almost certainly an error in the HG18 reference sequence. 1
25MAPT-R370WLowUncertainUncertain benign

Unknown, Heterozygous
0.155549Probably benign.1
26PCSK9-G670ELowUncertainUncertain benign

Unknown, Homozygous
0.888269This variant is likely benign. 1
27PTCH1-P1315LLowUncertainUncertain benign

Unknown, Heterozygous
0.29631Common polymorphism, presumed benign.1
28ABCC11-G180RLowUncertainUncertain benign

Unknown, Heterozygous
0.0976947This variant is associated with dry type ear wax (a benign trait) in a recessive manner.1
29SLC45A2-L374FLowUncertainUncertain benign

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