Genes affected
GK (HGNC:4289): (glycerol kinase) The protein encoded by this gene belongs to the FGGY kinase family. This protein is a key enzyme in the regulation of glycerol uptake and metabolism. It catalyzes the phosphorylation of glycerol by ATP, yielding ADP and glycerol-3-phosphate. Mutations in this gene are associated with glycerol kinase deficiency (GKD). Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Mar 2011]
GK Gene-Disease associations (from GenCC):
  • inborn glycerol kinase deficiency

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -6 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.025466949).
BP6
Variant X-30668097-A-G is Benign according to our data. Variant chrX-30668097-A-G is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 2370998.
BS2
High Hemizygotes in GnomAd4 at 2 AR,XL geneVariant has number of hemizygotes lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
