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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 11, 2024The c.2593G>C (p.G865R) alteration is located in exon 18 (coding exon 17) of the HK3 gene. This alteration results from a G to C substitution at nucleotide position 2593, causing the glycine (G) at amino acid position 865 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
