Genes affected
PSAT1 (HGNC:19129): (phosphoserine aminotransferase 1) This gene encodes a member of the class-V pyridoxal-phosphate-dependent aminotransferase family. The encoded protein is a phosphoserine aminotransferase and decreased expression may be associated with schizophrenia. Mutations in this gene are also associated with phosphoserine aminotransferase deficiency. Alternative splicing results in multiple transcript variants. Pseudogenes of this gene have been defined on chromosomes 1, 3, and 8. [provided by RefSeq, Jul 2013]

Neu-Laxova syndrome 2 Pathogenic:1
Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJun 23, 2023For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 1081). This variant is also known as c.delG107. This premature translational stop signal has been observed in individual(s) with phosphoserine aminotransferase deficiency (PMID: 17436247). This variant is present in population databases (rs774147367, gnomAD 0.004%). This sequence change creates a premature translational stop signal (p.Gly36Alafs*7) in the PSAT1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in PSAT1 are known to be pathogenic (PMID: 17436247, 25152457). -
