Gene: ALDH2 (aldehyde dehydrogenase 2 family member) Homo sapiens
Symbol: ALDH2
Name: aldehyde dehydrogenase 2 family member
Description: Exhibits aldehyde dehydrogenase (NAD+) activity. Predicted to be involved in carbohydrate metabolic process and ethanol oxidation. Localizes to the extracellular exosome. Implicated in several diseases, including alcohol use disorder; artery disease (multiple); diabetes mellitus (multiple); diabetic neuropathy; and liver disease (multiple). Biomarker of hepatocellular carcinoma.
Type: protein-coding
RefSeq Status: REVIEWED
Also known as: acetaldehyde dehydrogenase 2; aldehyde dehydrogenase 2; aldehyde dehydrogenase 2 family (mitochondrial); aldehyde dehydrogenase, mitochondrial; ALDH class 2; ALDH-E2; ALDHI; ALDM; liver mitochondrial ALDH; MGC1806; nucleus-encoded mitochondrial aldehyde dehydrogenase 2
