Summary
1LRP5-V667MHighUncertainUncertain pathogenic

Recessive, Carrier (Heterozygous)
0.0413646This variant has been implicated in causing osteoporosis-pseudoglioma syndrome in a recessive manner. The gene is strongly implicated in causing the disease, but an insufficient number of controls means this variant's observation lacks statistical significance. The condition manifests in childhood with early onset osteoporosis and eye problems.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
3HFE-C282YLowWell-establishedWell-established pathogenic

Recessive, Carrier (Heterozygous)
0.0494516This variant is associated with hereditary haemochromatosis, 80% of patients with that disease are homozygous for this variant. However, the penetrance is low, in Beutler et al. they note that only 1 of their 158 homozygotes met criteria for diagnosis with the condition.1
4KRT5-G138ELowLikelyLikely pathogenic

Unknown, Heterozygous
0.0521472This variant is associated with 1.25x increased risk of basal cell carcinoma (common skin cancer, rarely malignant).1
5AMPD1-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
6WFS1-R611HLowUncertainUncertain not reviewed

Recessive, Homozygous
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
7LRP5-A1330VLowUncertainUncertain pathogenic

Complex/Other, Heterozygous
0.110367In a study of a UK population this variant was associated with a small increased risk of osteoporosis and osteoporotic bone fractures, with each copy of the variant presumed to have an additive effect. A study in Chinese young men failed to find an association with peak bone density. 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
9TGIF1-P83ShiftLowUncertainUncertain pathogenic

Complex/Other, Homozygous
0.138889Severe variants in this gene are associated with holoprosencephaly disorders when combined with loss-of-function variants in SHH. Haploinsufficiency was identified in some families with this condition. It is unclear how likely this variant is to occur in combination with an SHH variant, or what phenotypic effect the variant would have on its own.1
10SP110-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
11TP53-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
12ERCC6-R1213GLowUncertainUncertain pathogenic

Recessive, Carrier (Heterozygous)
0.196877When homozygous, this variant may cause Cockayne Syndrome, which is a severe autosomal-recessive disorder characterized by abnormal early growth and development, abnormal sensitivity to sunlight, and premature aging. Cockayne Syndrome Type I and Type II lead to death in early childhood. Several other variants in the ERCC6 gene are linked to Cockayne Syndrome. This variant may also be linked to age-related macular degeneration like other ERCC6 variants, and has been linked to colorectal cancer in one study. 1
13ABCC6-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
14rs1544410LowUncertainUncertain 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
15NPC1-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
16KCNJ11-K23ELowLikelyLikely protective

Unknown, Heterozygous
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
17TOR1A-D216HLowLikelyLikely protective

Unknown, Heterozygous
0.102993This SNP has been shown to be benign and play a protective role against Dystonia. 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
19TYR-R402QLowWell-establishedWell-established benign

Complex/Other, Heterozygous
0.204964This is a frequent pigmentation polymorphism in Europeans that affects function of the Tyrosinase gene. It is associated with blue instead of green eyes and sun sensitivity. For the most part this variant is benign, but many individuals with ocular albinism (which affects only the eyes) carry this variant along with another more severe variant in the same gene.1
20CACNA1S-L458HLowLikelyLikely benign

Unknown, Heterozygous
0.27282Common polymorphism1
21COL6A3-D2831HLowLikelyLikely benign

Unknown, Heterozygous
0.0678565Probably benign, reported by Pan et al. as a presumed-nonpathogenic variant in the gene.1
22EFHC1-R182HLowLikelyLikely benign

Unknown, Heterozygous
0.0439673Probably benign. OMIM appears to incorrectly interpret literature as linking this variant to juvenile myoclonic epilepsy; the authors report it as a polymorphism.1
23PMS2-P470SLowLikelyLikely benign

Unknown, Heterozygous
0.374884Benign, common variant.1
24MLH1-I219VLowUncertainUncertain benign

Dominant, Heterozygous
0.239822Computational evidence, functional assays, and case/control studies suggest this variant is probably benign.1
25RPGRIP1-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
26CYP27A1-P384LLowUncertainUncertain benign

Unknown, Heterozygous
0.0177542Probably not pathogenic. Although predicted to be disruptive and treated by some as pathogenic, reports of this variant in cases were all linked with an upstream frameshift variant -- this supports the variant as a nonpathogenic ancestral polymorphism.1
27DYNC2H1-Q304LLowUncertainUncertain benign

Unknown, Heterozygous
0.0484135Presumed benign.1
28PKP2-L366PLowUncertainUncertain benign

Unknown, Heterozygous
0.221231This variant is a benign polymorphism. 1
29APOB-Y1422CLowUncertainUncertain benign

Unknown, Homozygous
0.999628This position is almost certainly an error in the HG18 reference sequence. 1
30AMPD1-P48LLowUncertainUncertain benign

Unknown, Heterozygous
0.0940695Probably benign, ancestral to15173240 pathogenic Q12X mutation.1
31FAH-R341WLowUncertainUncertain benign

Recessive, Carrier (Heterozygous)
0.0172895This variant shows pseudodeficiency for production of FAH protein which is connected with hereditary tyrosinemia type I. Pseudodeficiency was confirmed with site-directed mutagenesis and expression in a rabbit reticulocyte lysate system. The allelic frequency in 516 Norwegian controls was 0.022. 1
32PCSK9-G670ELowUncertainUncertain benign

Unknown, Heterozygous
0.888269This variant is likely benign. 1
33RP1-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
34ABCA4-R943QLowUncertainUncertain benign

Unknown, Heterozygous
0.0316044This is a polymorphism in a gene associated with Stargardt disease. Although it has a slight detectable effect in functional study, it is common in control groups and is not believed to have any significant pathogenic effect.1
35SLC45A2-L374FLowUncertainUncertain benign

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