Genes affected
VRK3 (HGNC:18996): (VRK serine/threonine kinase 3) This gene encodes a member of the vaccinia-related kinase (VRK) family of serine/threonine protein kinases. In both human and mouse, this gene has substitutions at several residues within the ATP binding motifs that in other kinases have been shown to be required for catalysis. In vitro assays indicate the protein lacks phosphorylation activity. The protein, however, likely retains its substrate binding capability. This gene is widely expressed in human tissues and its protein localizes to the nucleus. Alternative splicing results in multiple transcripts encoding different isoforms.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 10, 2023The c.1021G>T (p.A341S) alteration is located in exon 11 (coding exon 9) of the VRK3 gene. This alteration results from a G to T substitution at nucleotide position 1021, causing the alanine (A) at amino acid position 341 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
