Genes affected

GFPT2 (HGNC:4242): (glutamine-fructose-6-phosphate transaminase 2) Predicted to enable glutamine-fructose-6-phosphate transaminase (isomerizing) activity. Predicted to be involved in UDP-N-acetylglucosamine metabolic process; fructose 6-phosphate metabolic process; and protein N-linked glycosylation. Predicted to act upstream of or within cellular response to leukemia inhibitory factor. Predicted to be located in cytosol. Implicated in type 2 diabetes mellitus.

Ambry Genetics

Feb 06, 2023

The c.1837C>T (p.R613C) alteration is located in exon 17 (coding exon 17) of the GFPT2 gene. This alteration results from a C to T substitution at nucleotide position 1837, causing the arginine (R) at amino acid position 613 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
