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 Likely_benign. Variant got -4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.67).
• BP6: Variant 9-78297280-C-T is Benign according to our data. Variant chr9-78297280-C-T is described in ClinVar as [Likely_benign]. Clinvar id is 2037094.Status of the report is criteria_provided_single_submitter, 1 stars.
