Genes affected

ADH1C (HGNC:251): (alcohol dehydrogenase 1C (class I), gamma polypeptide) This gene encodes class I alcohol dehydrogenase, gamma subunit, which is a member of the alcohol dehydrogenase family. Members of this enzyme family metabolize a wide variety of substrates, including ethanol, retinol, other aliphatic alcohols, hydroxysteroids, and lipid peroxidation products. Class I alcohol dehydrogenase, consisting of several homo- and heterodimers of alpha, beta, and gamma subunits, exhibits high activity for ethanol oxidation to acetaldehyde, thus playing a major role in ethanol catabolism. Three genes encoding alpha, beta and gamma subunits are tandemly organized in a genomic segment as a gene cluster. An association between ADH1C polymorphism and alcohol dependence has not been established. [provided by RefSeq, Sep 2019]

The missense c.1066A>G(p.Ile356Val) variant in ADH1C gene has not been reported previously as a pathogenic variant nor as a benign variant, to our knowledge. The variant is reported with an allele frequency of 0.0004% in the gnomAD exomes database and is novel (not in any individuals) in 1000 Genomes database. This variant has not been reported to the ClinVar database. The amino acid change p.Ile356Val in ADH1C is predicted as conserved by GERP++ and PhyloP across 100 vertebrates. The amino acid Ile at position 356 is changed to a Val changing protein sequence and it might alter its composition and physico-chemical properties. For these reasons, this variant has been classified as Variant of Uncertain Significance (VUS). -
