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

  Inheritance: AR Classification: LIMITED Submitted by: G2P

ACMG classification

Our verdict: Uncertain_significance. The variant received 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
