Summary
1BRCA2-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
2TGFB1-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
3TP53-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
4HFE-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
5SP110-L425SLowUncertainUncertain pathogenic

Unknown, Heterozygous
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
6WFS1-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
7H6PD-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
8PRODH-R453CLowUncertainUncertain pathogenic

Recessive, Carrier (Heterozygous)
0.010132Associated with reduced proline oxidase activity, and may cause hyperprolemia in a recessive manner (when homozygous or compound heterozygous). Hyperprolemia, in turn, may be associated with schizophrenia.1
9ABCC6-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
10PRNP-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
11CFH-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
12ABCG5-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
13KCNJ11-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
14PMS2-P470SLowLikelyLikely benign

Unknown, Heterozygous
0.374884Benign, common variant.1
15RPGRIP1-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
16LOXL1-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
17SLC45A2-L374FLowUncertainUncertain benign

Unknown, Homozygous
0.691764Pigmentation allele for non-black hair, and consequently, possible increased susceptibility to malignant melanoma.1
18TPCN2-G734ELowUncertainUncertain benign

Unknown, Heterozygous
0.286166Pigmentation allele.1
19VWF-G2705RLowUncertainUncertain benign

Unknown, Heterozygous
0.0460123Probably benign, seems to be considered an uncommon polymorphism.1
20PKP2-L366PLowUncertainUncertain benign

Unknown, Heterozygous
0.221231This variant is a benign polymorphism. 1
21DSPP-R68WLowUncertainUncertain benign

Unknown, Heterozygous
0.143045Probably benign. One report linked this to causing dentinogenesis Imperfecta type II in a large Swedish family, but subsequent publications have observed this is a common variant and conclude it is a nonpathogenic polymorphism.1
22APOB-Y1422CLowUncertainUncertain benign

Unknown, Homozygous
0.999628This position is almost certainly an error in the HG18 reference sequence. 1
23ABCC11-G180RLowUncertainUncertain benign

Unknown, Heterozygous
0.0976947This variant is associated with dry type ear wax (a benign trait) in a recessive manner.1
24F5-M413TLowUncertainUncertain benign

Unknown, Heterozygous
0.0580963Presumed benign. This variant is not particularly rare and has not been reported to cause disease.1
25FMO3-V257MLowUncertainUncertain benign

Unknown, Heterozygous
0.0570738This common variant (HapMap allele frequency of 9.2%) appears to have no functional effect. OMIM has recorded it as having been seen homozygously in an individual with Trimethylaminuria, but Treacy et al. 1998 conclude it is a polymorphism.1
26PTCH1-P1315LLowUncertainUncertain benign

Unknown, Heterozygous
0.29631Common polymorphism, presumed benign.1
27PCSK9-G670ELowUncertainUncertain benign

Unknown, Homozygous
0.888269This variant is likely benign. 1
28MAPT-R370WLowUncertainUncertain benign

Unknown, Homozygous
0.155549Probably benign.1
29RP1-N985YLowUncertainUncertain benign

Unknown, Homozygous
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
