Genes affected

PFKFB3 (HGNC:8874): (6-phosphofructo-2-kinase/fructose-2,6-biphosphatase 3) The protein encoded by this gene belongs to a family of bifunctional proteins that are involved in both the synthesis and degradation of fructose-2,6-bisphosphate, a regulatory molecule that controls glycolysis in eukaryotes. The encoded protein has a 6-phosphofructo-2-kinase activity that catalyzes the synthesis of fructose-2,6-bisphosphate (F2,6BP), and a fructose-2,6-biphosphatase activity that catalyzes the degradation of F2,6BP. This protein is required for cell cycle progression and prevention of apoptosis. It functions as a regulator of cyclin-dependent kinase 1, linking glucose metabolism to cell proliferation and survival in tumor cells. Several alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Apr 2016]

Ambry Genetics

Oct 22, 2021

The c.1202A>T (p.D401V) alteration is located in exon 11 (coding exon 11) of the PFKFB3 gene. This alteration results from a A to T substitution at nucleotide position 1202, causing the aspartic acid (D) at amino acid position 401 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
