Genes affected

ALDH3B1 (HGNC:410): (aldehyde dehydrogenase 3 family member B1) This gene encodes a member of the aldehyde dehydrogenase protein family. Aldehyde dehydrogenases are a family of isozymes that may play a major role in the detoxification of aldehydes generated by alcohol metabolism and lipid peroxidation. The encoded protein is able to oxidize long-chain fatty aldehydes in vitro, and may play a role in protection from oxidative stress. Alternative splicing results in multiple transcript variants.

Ambry Genetics

Aug 12, 2021

The c.1324C>T (p.R442C) alteration is located in exon 10 (coding exon 9) of the ALDH3B1 gene. This alteration results from a C to T substitution at nucleotide position 1324, causing the arginine (R) at amino acid position 442 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
