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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 13, 2023The c.637G>A (p.G213R) alteration is located in exon 6 (coding exon 6) of the PFKL gene. This alteration results from a G to A substitution at nucleotide position 637, causing the glycine (G) at amino acid position 213 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
