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]

Ambry Genetics

Jun 30, 2023

The c.2710G>A (p.G904S) alteration is located in exon 19 (coding exon 18) of the HK3 gene. This alteration results from a G to A substitution at nucleotide position 2710, causing the glycine (G) at amino acid position 904 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
