Description

Variant summary: GCK c.394G>A (p.Asp132Asn) results in a conservative amino acid change located in the Hexokinase, N-terminal domain (IPR022672) of the encoded protein sequence. Three of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 8e-06 in 251338 control chromosomes (gnomAD). c.394G>A has been reported in the literature in individuals affected with Diabetes (Tinto_2008, Bansal_2017), and has been found segregating with disease in one family (Tinto_2008). These data indicate that the variant may be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Two ClinVar submitters have assessed the variant since 2014: both classified the variant as uncertain significance. Based on the evidence outlined above, the variant was classified as VUS-possibly pathogenic.
