PSAT1

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. [provided by RefSeq]

PSAT1

Catalyzes the reversible conversion of 3-phosphohydroxypyruvate to phosphoserine and of 3-hydroxy-2-oxo-4-phosphonooxybutanoate to phosphohydroxythreonine.

Phosphoserine aminotransferase deficiency (PSATD):
Characterized biochemically by low plasma and cerebrospinal fluid concentrations of serine and glycine and clinically by intractable seizures, acquired microcephaly, hypertonia, and psychomotor retardation.
Neu-Laxova syndrome 2 (NLS2):
A form of Neu-Laxova syndrome, a lethal, autosomal recessive multiple malformation syndrome characterized by ichthyosis, marked intrauterine growth restriction, microcephaly, short neck, limb deformities, hypoplastic lungs, edema, and central nervous system anomalies. These include lissencephaly, cerebellar hypoplasia and/or abnormal/agenesis of the corpus callosum. Abnormal facial features include severe proptosis with ectropion, hypertelorism, micrognathia, flattened nose, and malformed ears.
