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]

GLYCTK-AS1 (HGNC:41043): (GLYCTK antisense RNA 1)

ACMG classification

Our verdict: Benign. The variant received -13 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.8).
• BP6: Variant 3-52290363-C-T is Benign according to our data. Variant chr3-52290363-C-T is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 732033.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BP7: Synonymous conserved (PhyloP=0.871 with no splicing effect.
