Summary
1HABP2-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
2PPARG-P12AModerateUncertainUncertain not reviewed

Unknown, Heterozygous
0.08867821
3SERPINA1-E288VLowWell-establishedWell-established pathogenic

Recessive, Carrier (Heterozygous)
0.0304889This variant represents the PiS variant in alpha-1-antitrypsin deficiency where a homozygous individual has 60% enzymatic activity. This variant alone is unlikely to much effect, but 3-4% of heterozygotes are compound heterozygous with the more severe PiZ variant, which is associated with an increased risk of emphysema and COPD.1
4MTRR-I49MLowLikelyLikely pathogenic

Recessive, Homozygous
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
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
6NOD2-G908RLowLikelyLikely pathogenic

Unknown, Heterozygous
0.0106897This variant is associated with an increased susceptibility to Crohn's disease and other inflammatory bowel diseases (IBD). Assuming an overall prevalence of 0.5% for IBD, this variant implies an increased attributable risk of 2% (5x increased risk, for an overall risk of 2.5% of IBD for people with this variant).1
7AMPD1-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
8rs5186LowLikelyLikely pathogenic

Unknown, Homozygous
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
9CETP-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
10RNASEL-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
11TLR5-R392XLowUncertainUncertain pathogenic

Complex/Other, Heterozygous
0.0439673This variant is believed to impair the ability to generate an immune response to the flagella of the bacteria. It is weakly associated with an increased incidence of Legionnaires' Disease, p = 0.085, increased lifetime risk of disease ~0.88% (about twice average). The variant is also weakly associated with a reduced incidence of systemic lupus erythematosus, p = 0.165.1
12SP110-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
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
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
15WFS1-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
16TP53-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
17DPYD-M166VHighLikelyLikely pharmacogenetic

Unknown, Heterozygous
0.0778955Associated with DPYD deficiency and poor prognosis for chemotherapy w/ 5-flurorouracil. 1
18CYP2C9-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
19rs1544410LowUncertainUncertain 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
20NPC1-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
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
22LIG4-A3VLowUncertainUncertain protective

Dominant, Heterozygous
0.035843One report has associated this with a decreased risk of multiple myeloma.1
23ARSA-N350SLowWell-establishedWell-established benign

Unknown, Heterozygous
0.183199This common variant (HapMap 24.1% allele frequency) causes a loss of a glycosylation site (affecting the size of the protein when studied with gel electrophoresis) but does not affect enzyme activity or stability.1
24PMS2-P470SLowLikelyLikely benign

Unknown, Homozygous
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
26LOXL1-R141LLowUncertainUncertain benign

Complex/Other, Homozygous
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
27VWF-G2705RLowUncertainUncertain benign

Unknown, Heterozygous
0.0460123Probably benign, seems to be considered an uncommon polymorphism.1
28TAS2R38-A49PLowUncertainUncertain benign

Unknown, Homozygous
0.431121This variant is strongly associated with causing the "taster" phenotype of phenylthiocarbamine (PTC) in a dominant manner.1
29TYR-S192YLowUncertainUncertain benign

Unknown, Homozygous
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
30TAS2R38-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
31PCSK9-G670ELowUncertainUncertain benign

Unknown, Homozygous
0.888269This variant is likely benign. 1
32FANCA-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
33APOB-Y1422CLowUncertainUncertain benign

Unknown, Homozygous
0.999628This position is almost certainly an error in the HG18 reference sequence. 1
34AMPD1-P48LLowUncertainUncertain benign

Unknown, Heterozygous
0.0940695Probably benign, ancestral to15173240 pathogenic Q12X mutation.1
35MUSK-T100MLowUncertainUncertain benign

Unknown, Heterozygous
0.023413Probably benign.1
36PHYH-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
37RP1-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
38PTCH1-P1315LLowUncertainUncertain benign

Unknown, Homozygous
0.29631Common polymorphism, presumed benign.1
39PKP2-L366PLowUncertainUncertain benign

Unknown, Heterozygous
0.221231This variant is a benign polymorphism. 1
40SLC45A2-L374FLowUncertainUncertain benign

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