Genes affected

FPGS (HGNC:3824): (folylpolyglutamate synthase) This gene encodes the folylpolyglutamate synthetase enzyme. This enzyme has a central role in establishing and maintaining both cytosolic and mitochondrial folylpolyglutamate concentrations and, therefore, is essential for folate homeostasis and the survival of proliferating cells. This enzyme catalyzes the ATP-dependent addition of glutamate moieties to folate and folate derivatives. Alternative splicing results in transcript variants encoding different isoforms.

Ambry Genetics

Mar 16, 2023

The c.1247C>T (p.T416I) alteration is located in exon 13 (coding exon 13) of the FPGS gene. This alteration results from a C to T substitution at nucleotide position 1247, causing the threonine (T) at amino acid position 416 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
