Genes affected

HKDC1 (HGNC:23302): (hexokinase domain containing 1) This gene encodes a member of the hexokinase protein family. The encoded protein is involved in glucose metabolism, and reduced expression may be associated with gestational diabetes mellitus. High expression of this gene may also be associated with poor prognosis in hepatocarcinoma. [provided by RefSeq, Sep 2016]

Dec 21, 2022

The c.324G>C (p.E108D) alteration is located in exon 3 (coding exon 3) of the HKDC1 gene. This alteration results from a G to C substitution at nucleotide position 324, causing the glutamic acid (E) at amino acid position 108 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
