Summary
1PRPH-D141YHighUncertainUncertain pathogenic

Recessive, Carrier (Heterozygous)
0.00365206Hypothesized to cause ALS (or increased susceptibility) in a recessive manner, but this is based on a single observation and may lack statistical significance. The mutant protein appears to form abnormal aggregates.1
2HABP2-G534EModerateLikelyLikely pathogenic

Unknown, Heterozygous
0.0280721Known as the "Marburg I" polymorphism, this variant is associated with increased risk of coronary heart disease (CHD) in individuals with elevated cholesterol, triglyceride, and fibrinogen levels (5-fold risk of a CHD event, compared to 2-fold risk increase in people with the same risk factors but do not have this variant). In individuals without these elevated levels, however, carriers of the variant do not appear to have any increased risk of CHD.1
3APC-E1317QModerateUncertainUncertain pathogenic

Dominant, Heterozygous
0.00883228This rare variant has been hypothesized to increase risk of colon cancer. Later studies have contradicted this, finding no significant enrichment and concluding the variant does not increase risk.1
4PPARG-P12AModerateUncertainUncertain not reviewed

Unknown, Heterozygous
0.08867821
5COL4A1-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
6AMPD1-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
7MTRR-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
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
9RNASEL-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
10ATM-S49CLowUncertainUncertain pathogenic

Complex/Other, Heterozygous
0.00995349May be associated with a small increased risk of breast cancer.1
11CPN1-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
12WFS1-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
13TP53-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
14SP110-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
15HFE-S65CLowUncertainUncertain pathogenic

Recessive, Carrier (Heterozygous)
0.00976018A "mild" variant which may cause a very small increased risk of iron overload (hereditary hemachromatosis).1
16CYP2C9-R144CModerateWell-establishedWell-established pharmacogenetic

Unknown, Heterozygous
0.0970982This variant, also called CYP2C9*2, is a pharmacogenetic variant that modulates sensitivity for Warfarin (due to reduced metabolism). This variant is associated with Caucasians. The FDA has approved reduced recommended Warfarin dosage based on the presence of this variant.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
18IL7R-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
19TOR1A-D216HLowLikelyLikely protective

Unknown, Heterozygous
0.102993This SNP has been shown to be benign and play a protective role against Dystonia. 1
20KCNJ11-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
21MTR-D919GLowUncertainUncertain protective

Complex/Other, Homozygous
0.217234This variant was weakly associated with a protective effect vs. colorectal cancer, but only in individuals with low alcohol consumption. 1
22HEXA-R247WLowLikelyLikely benign

Recessive, Carrier (Heterozygous)
0.00288158Other variants in this gene cause Tay-Sachs disease. This variant causes "pseudodeficiency": some biochemical assays for detecting carriers of Tay-Sachs mutations will report also carriers of this variant (even though it does not cause the disease).1
23RPGRIP1-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
24VWF-G2705RLowUncertainUncertain benign

Unknown, Heterozygous
0.0460123Probably benign, seems to be considered an uncommon polymorphism.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
26GAA-D91NLowUncertainUncertain benign

Recessive, Carrier (Heterozygous)
0.0237033This is a rare but non-pathogenic coding polymorphism in GAA that creates variant allozyme, known as GAA*2. 1
27RP1-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
28PCSK9-G670ELowUncertainUncertain benign

Unknown, Homozygous
0.888269This variant is likely benign. 1
29MUSK-T100MLowUncertainUncertain benign

Unknown, Heterozygous
0.023413Probably benign.1
30FANCA-S1088FLowUncertainUncertain benign

Unknown, Heterozygous
0.0584681Probably benign. One report hypothesized this variant causing Fanconi Anemia, but the allele frequency (3-7%) is high enough to contradict a highly penetrant pathogenic effect. Later authors have concluded this is a polymorphism, not pathogenic.1
31APOB-Y1422CLowUncertainUncertain benign

Unknown, Homozygous
0.999628This position is almost certainly an error in the HG18 reference sequence. 1
32PHYH-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
33PTCH1-P1315LLowUncertainUncertain benign

Unknown, Homozygous
0.29631Common polymorphism, presumed benign.1
34TAS2R38-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
35SLC45A2-L374FLowUncertainUncertain benign

Unknown, Homozygous
0.691764Pigmentation allele for non-black hair, and consequently, possible increased susceptibility to malignant melanoma.1
36AMPD1-P48LLowUncertainUncertain benign

Unknown, Heterozygous
0.0940695Probably benign, ancestral to15173240 pathogenic Q12X mutation.1
37TAS2R38-A49PLowUncertainUncertain benign

Unknown, Heterozygous
0.431121This variant is strongly associated with causing the "taster" phenotype of phenylthiocarbamine (PTC) in a dominant manner.1
