Disease
[P5CS_HUMAN] Defects in ALDH18A1 are the cause of cutis laxa, autosomal recessive, type 3A (ARCL3A) [MIM:219150]. A syndrome characterized by facial dysmorphism with a progeroid appearance, large and late-closing fontanel, cutis laxa, joint hyperlaxity, athetoid movements and hyperreflexia, pre- and postnatal growth retardation, intellectual deficit, developmental delay, and ophthalmologic abnormalities.[1] [2]
Function
[P5CS_HUMAN] Bifunctional enzyme that converts glutamate to glutamate 5-semialdehyde, an intermediate in the biosynthesis of proline, ornithine and arginine.[3] [4]
