Summary
1LRP5-V667MHighUncertainUncertain pathogenic

Recessive, Carrier (Heterozygous)
0.0413646This variant has been implicated in causing osteoporosis-pseudoglioma syndrome in a recessive manner. The gene is strongly implicated in causing the disease, but an insufficient number of controls means this variant's observation lacks statistical significance. The condition manifests in childhood with early onset osteoporosis and eye problems.1
2MYO1A-G662EModerateUncertainUncertain pathogenic

Dominant, Heterozygous
0.0257483Although one report speculated that this variant may cause dominant, early-onset sensorineural hearing loss, the findings lacked statistical significance. Notably, this gene is not a clinically tested gene and another of the eight variants reported by these authors (S797F) has since been observed in a PGP participant with no symptoms of hearing loss.1
3PPARG-P12AModerateUncertainUncertain not reviewed

Unknown, Heterozygous
0.08867821
4COL4A1-Q1334HLowLikelyLikely pathogenic

Dominant, Heterozygous
0.324689This common variant has been associated with arterial stiffness and, in Japanese, a small increased risk of myocardial infarction (MI, a.k.a. heart attack). This last observation supported a dominant effect for this variant and, assuming a lifetime risk of 15% for MI, we estimate carriers have an additional risk of 0.5-3%.1
5NOD2-R702WLowLikelyLikely pathogenic

Complex/Other, Heterozygous
0.0334821NOD2 encodes a protein involved in bacterial recognition. This variant is associated with Crohn's disease in European populations, but not in Korean or Japanese groups.1
6KRT5-G138ELowLikelyLikely pathogenic

Unknown, Heterozygous
0.0521472This variant is associated with 1.25x increased risk of basal cell carcinoma (common skin cancer, rarely malignant).1
7LRP5-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
8ELAC2-S217LLowUncertainUncertain pathogenic

Complex/Other, Heterozygous
0.273471Reported to be associated with increased susceptibility to prostate cancer, but later studies weaken the hypothesis. Xu et al.'s meta-analysis concludes that there is a small but significant increased risk (OR = 1.13). Assuming a lifetime risk of 16% for prostate cancer we calculate this leads to an increased risk of ~1.5% (17.5% total).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
10H6PD-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
11TP53-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
12HFE-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
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
14rs1544410LowUncertainUncertain 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
15FUT2-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
16PRNP-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
17NPC1-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
18KCNJ11-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
19MTR-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
20LPL-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
21EFHC1-R182HLowLikelyLikely benign

Unknown, Heterozygous
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
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
23GALT-N314DLowUncertainUncertain benign

Unknown, Heterozygous
0.0716676This variant has an allele frequency of ~8% and is ancestral to "Duarte" / "Duarte 2" and "Duarte 1"/"Los Angeles" galactosemia variants. This variant is evolutionarily ancestral, and in vitro studies fail to support an impact of this variant on enzyme activity. Carney et al. instead implicate a 4 base deletion on the 5' of the GALT gene as being causal and linked to this variant. Galactosemia is typically screened and detected in infants and causes early, severe but nonspecific symptoms (digestive problems, lethargy, failure to thrive).1
24RP1-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
25PCSK9-G670ELowUncertainUncertain benign

Unknown, Homozygous
0.888269This variant is likely benign. 1
26FAH-R341WLowUncertainUncertain benign

Recessive, Carrier (Heterozygous)
0.0172895This variant shows pseudodeficiency for production of FAH protein which is connected with hereditary tyrosinemia type I. Pseudodeficiency was confirmed with site-directed mutagenesis and expression in a rabbit reticulocyte lysate system. The allelic frequency in 516 Norwegian controls was 0.022. 1
27SLC45A2-L374FLowUncertainUncertain benign

Unknown, Homozygous
0.691764Pigmentation allele for non-black hair, and consequently, possible increased susceptibility to malignant melanoma.1
28ENPP1-R774CLowUncertainUncertain benign

Unknown, Heterozygous
0.0258412Tentatively classified as benign. Initially reported as a recessive cause of infantile arterial calcification, but with no statistical significance. Other variants have been implicated as causal in these cases this variant. 5% allele frequency in caucasians contradicts this variant as having any highly pathogenic effect.1
