Genes affected

HK3 (HGNC:4925): (hexokinase 3) Hexokinases phosphorylate glucose to produce glucose-6-phosphate, the first step in most glucose metabolism pathways. This gene encodes hexokinase 3. Similar to hexokinases 1 and 2, this allosteric enzyme is inhibited by its product glucose-6-phosphate. [provided by RefSeq, Apr 2009]

Oct 13, 2023

The c.2622C>G (p.H874Q) alteration is located in exon 18 (coding exon 17) of the HK3 gene. This alteration results from a C to G substitution at nucleotide position 2622, causing the histidine (H) at amino acid position 874 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
