Genes affected
ALDH3A2 (HGNC:403): (aldehyde dehydrogenase 3 family member A2) Aldehyde dehydrogenase isozymes are thought to play a major role in the detoxification of aldehydes generated by alcohol metabolism and lipid peroxidation. This gene product catalyzes the oxidation of long-chain aliphatic aldehydes to fatty acid. Mutations in the gene cause Sjogren-Larsson syndrome. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

not provided Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Apr 07, 2023 | For these reasons, this variant has been classified as Pathogenic. This variant disrupts a region of the ALDH3A2 protein in which other variant(s) (p.Leu27Pro) have been determined to be pathogenic (PMID: 11408337). This suggests that this is a clinically significant region of the protein, and that variants that disrupt it are likely to be disease-causing. ClinVar contains an entry for this variant (Variation ID: 552666). This variant has not been reported in the literature in individuals affected with ALDH3A2-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change affects the initiator methionine of the ALDH3A2 mRNA. The next in-frame methionine is located at codon 33. - |
