Phosphoserine aminotransferase (PSA) also known as phosphohydroxythreonine aminotransferase (PSAT) is an enzyme that in humans is encoded by the PSAT1 gene.[5]

The protein encoded by this gene is likely a phosphoserine aminotransferase, based on similarity to proteins in mouse, rabbit, and Drosophila. Alternative splicing of this gene results in two transcript variants encoding different isoforms.[5]

Clinical significance

Homozygous or compound heterozygous mutations in PSAT1 cause Neu–Laxova syndrome[6] and phosphoserine aminotransferase deficiency.[7]
