Mar 09, 2018

This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. -

Some studies observed an association between VKORC1 -1639G>A (rs9923231) with thromboembolism (Dubovyk 2016, Kumari 2019). Our study suggests a possible protective effect for the -1639A allele against venous thromboembolism. References Dubovyk YI, Harbuzova VY, Ataman A V.

PharmGKB Level of Evidence 2A: Variants in Level 2A clinical annotations are found in PharmGKB’s Tier 1 Very Important Pharmacogenes (VIPs). These variants are in known pharmacogenes, implying causation of drug phenotype is more likely. These clinical annotations describe variant-drug combinations with a moderate level of evidence supporting the association. For example, the association may be found in multiple cohorts, but there may be a minority of studies that do not support the majority assertion. Level 2A clinical annotations must be supported by at least two independent publications. Drug-variant association: Toxicity
