Genes affected

ADH1B (HGNC:250): (alcohol dehydrogenase 1B (class I), beta polypeptide) The protein encoded by this gene 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. This encoded protein, consisting of several homo- and heterodimers of alpha, beta, and gamma subunits, exhibits high activity for ethanol oxidation and plays 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. Two transcript variants encoding different isoforms have been found for this gene.

The c.938G>A (p.R313H) alteration is located in exon 7 (coding exon 7) of the ADH1B gene. This alteration results from a G to A substitution at nucleotide position 938, causing the arginine (R) at amino acid position 313 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
