Genes affected
PFKL (HGNC:8876): (phosphofructokinase, liver type) This gene encodes the liver (L) subunit of an enzyme that catalyzes the conversion of D-fructose 6-phosphate to D-fructose 1,6-bisphosphate, which is a key step in glucose metabolism (glycolysis). This enzyme is a tetramer that may be composed of different subunits encoded by distinct genes in different tissues. Alternative splicing results in multiple transcript variants.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 07, 2024The c.673G>C (p.A225P) alteration is located in exon 7 (coding exon 7) of the PFKL gene. This alteration results from a G to C substitution at nucleotide position 673, causing the alanine (A) at amino acid position 225 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
