Genes affected
GLYCTK (HGNC:24247): (glycerate kinase) This locus encodes a member of the glycerate kinase type-2 family. The encoded enzyme catalyzes the phosphorylation of (R)-glycerate and may be involved in serine degradation and fructose metabolism. Decreased activity of the encoded enzyme may be associated with the disease D-glyceric aciduria. Alternatively spliced transcript variants have been described. [provided by RefSeq, Jan 2009]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 31, 2024The c.115A>G (p.R39G) alteration is located in exon 2 (coding exon 1) of the GLYCTK gene. This alteration results from a A to G substitution at nucleotide position 115, causing the arginine (R) at amino acid position 39 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
