Genes affected

ADH6 (HGNC:255): (alcohol dehydrogenase 6 (class V)) This gene encodes class V alcohol dehydrogenase, which is a member of the alcohol dehydrogenase family. Members of this family metabolize a wide variety of substrates, including ethanol, retinol, other aliphatic alcohols, hydroxysteroids, and lipid peroxidation products. This gene is expressed in the stomach as well as in the liver, and it contains a glucocorticoid response element upstream of its 5' UTR, which is a steroid hormone receptor binding site. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.649G>A (p.A217T) alteration is located in exon 6 (coding exon 6) of the ADH6 gene. This alteration results from a G to A substitution at nucleotide position 649, causing the alanine (A) at amino acid position 217 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
