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]
HKDC1 Gene-Disease associations (from GenCC):
  • retinitis pigmentosa
