About ALDH18A1

Cytogenetic location: 10q24.1 Genomic coordinates (GRCh38): 10:95,605,941-95,656,711 (from NCBI)

This gene has 5 transcripts (splice variants), 261 orthologues and is associated with 14 phenotypes. Ubiquitous expression in duodenum (RPKM 41.4), small intestine (RPKM 34.7) and 25 other tissues.

Summary

This gene is a member of the aldehyde dehydrogenase family and encodes a bifunctional ATP- and NADPH-dependent mitochondrial Enzyme with both gamma-glutamyl kinase and gamma-glutamyl phosphate reductase activities. The encoded protein catalyzes the reduction of glutamate to delta1-pyrroline-5-carboxylate, a critical step in the de novo biosynthesis of proline, ornithine and arginine. Mutations in this gene lead to hyperammonemia, hypoornithinemia, hypocitrullinemia, hypoargininemia and hypoprolinemia and may be associated with neurodegeneration, cataracts and connective tissue diseases. Alternatively spliced transcript variants, encoding different isoforms, have been described for this gene. [provided by RefSeq, Jul 2008]
