1COL4A1-Q1334HLowLikelyLikely pathogenic

Dominant, Homozygous
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
2CETP-A390PLowLikelyLikely pathogenic

Unknown, Heterozygous
0.0388548This variant is associated with slightly lower HDL (good) cholesterol, although it has a negligible effect (around 2 mg/dl).1
3MTRR-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
4ELAC2-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
5RNASEL-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
6CPN1-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
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
8TP53-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
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
10SLC5A2-N654SLowUncertainUncertain pathogenic

Recessive, Carrier (Heterozygous)
0.00706451Some authors report this rare variant as a nonpathogenic polymorphism, others suggest it may cause renal glucosuria in a recessive manner when compound heterozygous with other pathogenic variants.1
11DPYD-M166VHighLikelyLikely pharmacogenetic

Unknown, Heterozygous
0.0778955Associated with DPYD deficiency and poor prognosis for chemotherapy w/ 5-flurorouracil. 1
12TPMT-Y240CLowWell-establishedWell-established pharmacogenetic

Complex/Other, Heterozygous
0.0461825Alone, this variant is known as TPMT*3C -- but often, especially in Caucasians, it is found together with another nonsynonymous variant (A154T) to produce the TPMT*3A variant. Both variants are associated with loss of thiopurine methyltransferase (TPMT) activity, although *3C is milder than *3A. Inability to metabolize thiopurine drugs can lead to severe adverse reactions. Heterozygotes may be advised to take a reduced dosage due to reduced metabolism of the drug.1
13TPMT-A154TLowLikelyLikely pharmacogenetic

Recessive, Carrier (Heterozygous)
0.0280774Usually this variant is found in combination Y240C, forming the TPMT*3A variant. When alone, this variant produces the *3B variant. Both variants are associated with loss of thiopurine methyltransferase (TPMT) activity. Inability to metabolize thiopurine drugs can lead to severe adverse reactions. Heterozygotes may be advised to take a reduced dosage due to reduced metabolism of the drug.1
14ABCC6-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
15rs1544410LowUncertainUncertain pharmacogenetic

Unknown, Homozygous
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
16FUT2-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
17CASP10-V410ILowLikelyLikely protective

Dominant, Heterozygous
0.0474066Reported to have a protective effect on breast cancer. If the lifetime risk of breast cancer is 12%, women with this variant may have a lower risk of 8-9% (30% less than average).1
18CFH-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
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
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, Heterozygous
0.217234This variant was weakly associated with a protective effect vs. colorectal cancer, but only in individuals with low alcohol consumption. 1
22IRS2-G1057DLowUncertainUncertain protective

Unknown, Heterozygous
0.232615a.k.a Gly1057Asp, insulin receptor substrate-2 IRS2. The rs1805097(G) allele is associated with the Gly, and the (A) allele with Asp. A longevity study concluded that rs1805097(A;A) individuals were about twice as likely to live over 85 y/o (odds ratio 2.03, CI:1.39-2.99, p = .0003). 1
23LPL-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
24PMS2-P470SLowLikelyLikely benign

Unknown, Heterozygous
0.374884Benign, common variant.1
25MLH1-I219VLowUncertainUncertain benign

Dominant, Homozygous
0.239822Computational evidence, functional assays, and case/control studies suggest this variant is probably benign.1
26RPGRIP1-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
27TAS2R38-A49PLowUncertainUncertain benign

Unknown, Heterozygous
0.431121This variant is strongly associated with causing the "taster" phenotype of phenylthiocarbamine (PTC) in a dominant manner.1
28TCIRG1-R56WLowUncertainUncertain benign

Unknown, Homozygous
0.0441778Probably benign. One publication implicates the variant in causing osteopetrosis, but this is contradicted by the relatively high allele frequency for the variant in Caucasians (5%, 1 in 400 homozygous) while that disease is extremely rare (1 in 250,000).1
29PCSK9-G670ELowUncertainUncertain benign

Unknown, Heterozygous
0.888269This variant is likely benign. 1
30MAPT-R370WLowUncertainUncertain benign

Unknown, Heterozygous
0.155549Probably benign.1
31KRT85-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
32APOB-Y1422CLowUncertainUncertain benign

Unknown, Homozygous
0.999628This position is almost certainly an error in the HG18 reference sequence. 1
33PHYH-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
34PKP2-L366PLowUncertainUncertain benign

Unknown, Heterozygous
0.221231This variant is a benign polymorphism. 1
35SLC45A2-L374FLowUncertainUncertain benign

Unknown, Homozygous
0.691764Pigmentation allele for non-black hair, and consequently, possible increased susceptibility to malignant melanoma.1
36RP1-N985YLowUncertainUncertain benign

Unknown, Heterozygous
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
37PTCH1-P1315LLowUncertainUncertain benign

Unknown, Heterozygous
0.29631Common polymorphism, presumed benign.1
38TAS2R38-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
