Summary
1TSEN54-A307SHighLikelyLikely pathogenic

Recessive, Carrier (Heterozygous)
0.000839865Causes pontocerebellar hypoplasia (a serious deformity in brain development) in a recessive manner.1
2COL4A1-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
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
4APOA5-S19WLowLikelyLikely pathogenic

Unknown, Heterozygous
0.0646151This variant, also known as APOA5*3, is associated with higher plasma triglyceride concentrations but no significant correlation with coronary artery disease itself has been found.1
5WFS1-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
6TP53-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
7SP110-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
8RET-Y791FLowUncertainUncertain pathogenic

Unknown, Heterozygous
0.00130136Several publications asserted this variant caused familial medullary thyroid cancer in a dominant manner. However, a 2010 publication by Erlic et al. examined a larger set of controls, finding the variant no more common in cases than it was in controls. These authors conclude that the variant is not a serious cause of the disease, although they could not rule out a small effect on risk.1
9FUT2-W154XModerateWell-establishedWell-established protective

Recessive, Homozygous
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
10KCNJ11-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
11OCA2-R419QLowLikelyLikely benign

Unknown, Heterozygous
0.0565161This variant is associated with eye color, as is OCA2 R305W. Individuals with this variant are reported to be more likely to have green/hazel eyes as opposed to blue/gray eyes. Other variants in this gene are associated with oculocutaneous albinism (albinism which involves skin and eyes).1
12PMS2-P470SLowLikelyLikely benign

Unknown, Heterozygous
0.374884Benign, common variant.1
13GUCY2D-A52SLowUncertainUncertain benign

Recessive, Carrier (Heterozygous)
0.21016One publication suggested that this variant possibly causes Leber's congenital amaurosis in a recessive manner, but the frequency data (36% in 1000 genomes) contradicts any significant pathogenic effect.1
14BRCA1-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
15APOB-Y1422CLowUncertainUncertain benign

Unknown, Homozygous
0.999628This position is almost certainly an error in the HG18 reference sequence. 1
16GALT-N314DLowUncertainUncertain benign

Unknown, Heterozygous
0.0716676This variant has an allele frequency of ~8% and is ancestral to "Duarte" / "Duarte 2" and "Duarte 1"/"Los Angeles" galactosemia variants. This variant is evolutionarily ancestral, and in vitro studies fail to support an impact of this variant on enzyme activity. Carney et al. instead implicate a 4 base deletion on the 5' of the GALT gene as being causal and linked to this variant. Galactosemia is typically screened and detected in infants and causes early, severe but nonspecific symptoms (digestive problems, lethargy, failure to thrive).1
17MAPT-R370WLowUncertainUncertain benign

Unknown, Heterozygous
0.155549Probably benign.1
18RP1-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
19PCSK9-G670ELowUncertainUncertain benign

Unknown, Heterozygous
0.888269This variant is likely benign. 1
20TPCN2-G734ELowUncertainUncertain benign

Unknown, Heterozygous
0.286166Pigmentation allele.1
21SLC45A2-L374FLowUncertainUncertain benign

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