Genes affected

KYAT1 (HGNC:1564): (kynurenine aminotransferase 1) This gene encodes a cytosolic enzyme that is responsible for the metabolism of cysteine conjugates of certain halogenated alkenes and alkanes. This metabolism can form reactive metabolites leading to nephrotoxicity and neurotoxicity. Increased levels of this enzyme have been linked to schizophrenia. Multiple transcript variants that encode different isoforms have been identified for this gene. [provided by RefSeq, Jul 2008]

The c.1138C>T (p.P380S) alteration is located in exon 12 (coding exon 11) of the KYAT1 gene. This alteration results from a C to T substitution at nucleotide position 1138, causing the proline (P) at amino acid position 380 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
