Genes affected

ADH7 (HGNC:256): (alcohol dehydrogenase 7 (class IV), mu or sigma polypeptide) This gene encodes class IV alcohol dehydrogenase 7 mu or sigma subunit, 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. The enzyme encoded by this gene is inefficient in ethanol oxidation, but is the most active as a retinol dehydrogenase; thus it may participate in the synthesis of retinoic acid, a hormone important for cellular differentiation. The expression of this gene is much more abundant in stomach than liver, thus differing from the other known gene family members. Alternative splicing results in multiple transcript variants.

ACMG classification

Verdict is Benign. Variant got -10 ACMG points.

• PM1: In a binding_site (size 0) in uniprot entity ADH7_HUMAN
• BP4: Computational evidence support a benign effect (MetaRNN=0.002137661).
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.103 is higher than 0.05.
