Genes affected

VRK2 (HGNC:12719): (VRK serine/threonine kinase 2) This gene encodes a member of the vaccinia-related kinase (VRK) family of serine/threonine protein kinases. The encoded protein acts as an effector of signaling pathways that regulate apoptosis and tumor cell growth. Variants in this gene have been associated with schizophrenia. Alternative splicing results in multiple transcript variants that differ in their subcellular localization and biological activity. [provided by RefSeq, Jan 2014]

The c.311A>C (p.Y104S) alteration is located in exon 5 (coding exon 4) of the VRK2 gene. This alteration results from a A to C substitution at nucleotide position 311, causing the tyrosine (Y) at amino acid position 104 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
