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 GeneticsSep 20, 2024The c.262C>T (p.R88C) alteration is located in exon 4 (coding exon 4) of the PFKL gene. This alteration results from a C to T substitution at nucleotide position 262, causing the arginine (R) at amino acid position 88 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
