Summary
1APOE-C130RHighWell-establishedWell-established pathogenic

Complex/Other, Heterozygous
0.135392This is generally known as the ApoE4 allele of ApoE and is associated with increased risk of Alzheimer's. 20-25% of individuals are heterozygous for this variant, and 1-2% are homozygous. Data from Khachaturian et al. suggests an average 7% of all individuals developed Alzheimer's by the age of 80; when this is split by ApoE4 status: 10% of ApoE4 heterozygotes (3% increased attributable risk), 40% of ApoE4 homozygotes (33% increased attributable risk), and 5% of non-carriers (2% decreased attributable risk). Notably, their model suggests 70-75% of people would eventually develop Alzheimer's by the age of 100 regardless of ApoE4 genotype (and 25-30% are resistant, regardless of genotype), but that ApoE4 variants shift the disease onset to occur significantly earlier (4 years earlier for heterozygous carriers, 13 years for homozygotes).1
2RYR2-G1886SHighUncertainUncertain pathogenic

Recessive, Carrier (Heterozygous)
0.0613424Reported to cause arrhythmogenic right ventricular cardiomyopathy when compound heterozygous with G1885E, although this finding is weakened after correcting for multiple hypotheses and it is unclear what penetrance such a genotype might have, if it is causal.1
3COL9A3-R103WModerateLikelyLikely pathogenic

Dominant, Heterozygous
0.0480573Carriers of this collagen variant are associated with having a significantly increased risk of lumbar disc disease (~11% total risk compared to a typical risk of 4%). 1
4HABP2-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
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
6MBL2-G54DLowLikelyLikely pathogenic

Recessive, Carrier (Heterozygous)
0.103923This variant is associated with mannose binding protein deficiency which leads to impaired complement system immune response to mannose-rich pathogens. Patients homozygous for this allele or compound heterozygous are likely to have increased susceptibility to infection, but Hellemann et al. report heterosis for intensive care outcomes in heterozygous subjects. The wild-type version of this gene is known as variant allele A, while this is called variant allele B. See R52C (variant D) and G57E (variant C).1
7KRT5-G138ELowLikelyLikely pathogenic

Unknown, Heterozygous
0.0521472This variant is associated with 1.25x increased risk of basal cell carcinoma (common skin cancer, rarely malignant).1
8AMPD1-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
9POLG-Q1236HLowUncertainUncertain pathogenic

Complex/Other, Heterozygous
0.0581893Generally a nonpathogenic polymorphism, but may have a modifier effect that increases severity when combined in cis with other pathogenic variants.1
10KDR-C482RLowUncertainUncertain pathogenic

Complex/Other, Heterozygous
0.0209147Hypothesized to cause a higher risk of benign neonatal hemangiomas (which are seen in 10% of children). However, observations lacked statistical significance.1
11TGFB1-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
12TP53-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
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
14HFE-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
15H6PD-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
16SP110-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
17DPYD-M166VHighLikelyLikely pharmacogenetic

Unknown, Heterozygous
0.0778955Associated with DPYD deficiency and poor prognosis for chemotherapy w/ 5-flurorouracil. 1
18TPMT-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
19TPMT-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
20ABCC6-R1268QLowUncertainUncertain pharmacogenetic

Unknown, Homozygous
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
21PRNP-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
22NPC1-H215RLowLikelyLikely protective

Complex/Other, Homozygous
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
23ABCG5-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
24IL7R-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
25KCNJ11-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
26LIG4-A3VLowUncertainUncertain protective

Dominant, Heterozygous
0.035843One report has associated this with a decreased risk of multiple myeloma.1
27MTR-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
28PMS2-P470SLowLikelyLikely benign

Unknown, Heterozygous
0.374884Benign, common variant.1
29MLH1-I219VLowUncertainUncertain benign

Dominant, Heterozygous
0.239822Computational evidence, functional assays, and case/control studies suggest this variant is probably benign.1
30RPGRIP1-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
31SDHD-H50RLowUncertainUncertain benign

Unknown, Heterozygous
0.00659974Probably benign. Other mutations in this gene are implicated in causing hereditary paraganglioma or pheochromocytoma syndromes, but this variant is also found in unaffected controls and is considered a nonpathogenic polymorphism by most authors that have reported it.1
32TPCN2-G734ELowUncertainUncertain benign

Unknown, Heterozygous
0.286166Pigmentation allele.1
33GAA-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
34PCSK9-G670ELowUncertainUncertain benign

Unknown, Homozygous
0.888269This variant is likely benign. 1
35F5-D2222GLowUncertainUncertain benign

Unknown, Heterozygous
0.0448968Other mutations in this gene are associated with Factor 5 deficiency. There is no literature implicating this variant, however, and it is fairly common in the population (3.8% in HapMap), and so it is currently labeled as benign.1
36APOB-Y1422CLowUncertainUncertain benign

Unknown, Homozygous
0.999628This position is almost certainly an error in the HG18 reference sequence. 1
37AMPD1-P48LLowUncertainUncertain benign

Unknown, Heterozygous
0.0940695Probably benign, ancestral to15173240 pathogenic Q12X mutation.1
38F5-M413TLowUncertainUncertain benign

Unknown, Heterozygous
0.0580963Presumed benign. This variant is not particularly rare and has not been reported to cause disease.1
39RP1-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
40TAS2R38-I296VLowUncertainUncertain benign

Unknown, Homozygous
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
41SLC45A2-L374FLowUncertainUncertain benign

Unknown, Homozygous
0.691764Pigmentation allele for non-black hair, and consequently, possible increased susceptibility to malignant melanoma.1
42TAS2R38-A49PLowUncertainUncertain benign

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