Summary
1PKD1-R4276WHighUncertainUncertain pathogenic

Dominant, Heterozygous
0.00200401Reported to cause autosomal dominant polycystic kidney disease, but it has been seen in a confirmed-healthy PGP participant and one other presumed-healthy control genome (overall frequency in randomly chosen controls is 1.7%).1
2SLC9A3R1-R153QModerateUncertainUncertain pathogenic

Dominant, Heterozygous
0.0034393This variant was reported in a small family, associated with kidney stones. This gene is strongly associated with causing kidney stones and osteoporosis, and the variant is computationally predicted to be damaging, but the reported cases for this variant were too few to establish any statistical significance.1
3COL4A1-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
4PRF1-A91VLowLikelyLikely pathogenic

Complex/Other, Heterozygous
0.0325339This variant may be associated with a slightly increased susceptibility to some rare blood disorders, in particular autoimmune proliferative disease, if combined with a more severe mutation elsewhere. Most reports lack statistical significance.1
5MTRR-I49MLowLikelyLikely pathogenic

Recessive, Carrier (Heterozygous)
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
6rs5186LowLikelyLikely pathogenic

Unknown, Heterozygous
0.214878This common noncoding genetic variant has an allele frequency of ~30% and is associated with an increased risk of hypertension. If ~25% of non-carriers have hypertension, Bonnardeaux et al's data predict ~4% increased risk of hypertension per copy of this variant. This SNP is in the 3' noncoding region of the AGTR1 transcript (angiotensin II type 1 receptor), also known as AT2R1 or AT1R, which is a target of hypertension drugs.1
7WFS1-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
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
9HFE-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
10TP53-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
11SP110-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
12MEFV-P369SLowUncertainUncertain pathogenic

Recessive, Carrier (Heterozygous)
0.00511247Weak evidence associating this with familial mediterranean fever, but there is a fairly high frequency of this allele. This variant might cause increased susceptibility to the disease but there is not enough evidence to be significant.1
13H6PD-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
14DPYD-M166VHighLikelyLikely pharmacogenetic

Unknown, Heterozygous
0.0778955Associated with DPYD deficiency and poor prognosis for chemotherapy w/ 5-flurorouracil. 1
15rs1544410LowUncertainUncertain 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
16ABCC6-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
17FUT2-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
18PRNP-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
19NPC1-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
20TOR1A-D216HLowLikelyLikely protective

Unknown, Heterozygous
0.102993This SNP has been shown to be benign and play a protective role against Dystonia. 1
21IL7R-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
22KCNJ11-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
23MLH1-I219VLowUncertainUncertain benign

Dominant, Homozygous
0.239822Computational evidence, functional assays, and case/control studies suggest this variant is probably benign.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
26PCSK9-G670ELowUncertainUncertain benign

Unknown, Homozygous
0.888269This variant is likely benign. 1
27FAH-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
28BRCA1-Q356RLowUncertainUncertain benign

Unknown, Heterozygous
0.0462911One common variant associated this variant with an increased risk of breast cancer, but a more recent, larger study found no association.1
29HR-T1022ALowUncertainUncertain benign

Recessive, Carrier (Heterozygous)
0.0969511Probably benign. One study implicated it in causing alopecia universalis, but a later report noted the variant has an allele frequency inconsistent with the rarity of that disease.1
30SLC45A2-L374FLowUncertainUncertain benign

Unknown, Homozygous
0.691764Pigmentation allele for non-black hair, and consequently, possible increased susceptibility to malignant melanoma.1
31TAS2R38-A49PLowUncertainUncertain benign

Unknown, Heterozygous
0.431121This variant is strongly associated with causing the "taster" phenotype of phenylthiocarbamine (PTC) in a dominant manner.1
32TAS2R38-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
33TPCN2-G734ELowUncertainUncertain benign

Unknown, Heterozygous
