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]

ACMG classification

Verdict is Uncertain_significance. Variant got 3 ACMG points.

• PVS1: Loss of function variant, product does not undergo nonsense mediated mRNA decay. Variant is located in the 3'-most exon, not predicted to undergo nonsense mediated mRNA decay. Fraction of 0.0809 CDS is truncated, and there are 1 pathogenic variants in the truncated region.
• PP5: Variant 9-78328996-CCGGG-AGACCT is Pathogenic according to our data. Variant chr9-78328996-CCGGG-AGACCT is described in ClinVar as [Pathogenic]. Clinvar id is 156362.Status of the report is no_assertion_criteria_provided, 0 stars.
