Genes affected

GLYAT (HGNC:13734): (glycine-N-acyltransferase) The glycine-N-acyltransferase protein conjugates glycine with acyl-CoA substrates in the mitochondria. The protein is thought to be important in the detoxification of endogenous and xenobiotic acyl-CoA's. Two transcript variants encoding different isoforms have been found for this gene.

Collection Method: clinical testing

The c.646C>A (p.P216T) alteration is located in exon 6 (coding exon 5) of the GLYAT gene. This alteration results from a C to A substitution at nucleotide position 646, causing the proline (P) at amino acid position 216 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
