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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 29, 2023The c.719C>T (p.A240V) alteration is located in exon 7 (coding exon 6) of the ALDH3B1 gene. This alteration results from a C to T substitution at nucleotide position 719, causing the alanine (A) at amino acid position 240 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
