Genes affected

TLK1 (HGNC:11841): (tousled like kinase 1) The protein encoded by this gene is a serine/threonine kinase that may be involved in the regulation of chromatin assembly. The encoded protein is only active when it is phosphorylated, and this phosphorylation is cell cycle-dependent, with the maximal activity of this protein coming during S phase. The catalytic activity of this protein is diminished by DNA damage and by blockage of DNA replication. Three transcript variants encoding different isoforms have been found for this gene.

The c.752G>A (p.R251Q) alteration is located in exon 9 (coding exon 9) of the TLK1 gene. This alteration results from a G to A substitution at nucleotide position 752, causing the arginine (R) at amino acid position 251 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
