Involvement in disease
Defects in ALDH18A1 are the cause of mental retardation-joint hypermobility-skin laxity with or without metabolic abnormalities (MRJHSL) [MIM:612652]. Clinical manifestations include microcephaly, progressive neurologic dysfunction, mental retardation, progeroid appearance, joint hypermobility, skin laxity and hyperelasticity, cataracts. Some patients manifest metabolic disturbances such as hyperammonemia, hypoornithinemia, hypocitrullinemia, hypoargininemia and hypoprolinemia.
In the N-terminal section; belongs to the glutamate 5-kinase family. In the C-terminal section; belongs to the gamma-glutamyl phosphate reductase family.
P5CS catalyzes the ATP- and NADPH-dependent conversion of L-glutamate to glutamic gamma-semialdehyde, which is the metabolic precursor for proline biosynthesis. There are 2 isoforms produced by alternative splicing.
