Genes affected

ADH4 (HGNC:252): (alcohol dehydrogenase 4 (class II), pi polypeptide) This gene encodes class II alcohol dehydrogenase 4 pi 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 II alcohol dehydrogenase is a homodimer composed of 2 pi subunits. It exhibits a high activity for oxidation of long-chain aliphatic alcohols and aromatic alcohols and is less sensitive to pyrazole. This gene is localized to chromosome 4 in the cluster of alcohol dehydrogenase genes. [provided by RefSeq, Jul 2008]

The c.563C>T (p.A188V) alteration is located in exon 5 (coding exon 5) of the ADH4 gene. This alteration results from a C to T substitution at nucleotide position 563, causing the alanine (A) at amino acid position 188 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
