Genes affected

PFKP (HGNC:8878): (phosphofructokinase, platelet) This gene encodes a member of the phosphofructokinase A protein family. The encoded enzyme is the platelet-specific isoform of phosphofructokinase and plays a key role in glycolysis regulation. This gene may play a role in metabolic reprogramming in some cancers, including clear cell renal cell carcinomas, and cancer of the bladder, breast, and lung. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Sep 2016]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.22G>C (p.A8P) alteration is located in exon 1 (coding exon 1) of the PFKP gene. This alteration results from a G to C substitution at nucleotide position 22, causing the alanine (A) at amino acid position 8 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
