Genes affected

CCNK (HGNC:1596): (cyclin K) The protein encoded by this gene is a member of the transcription cyclin family. These cyclins may regulate transcription through their association with and activation of cyclin-dependent kinases (CDK) that phosphorylate the C-terminal domain (CTD) of the large subunit of RNA polymerase II. This gene product may play a dual role in regulating CDK and RNA polymerase II activities. [provided by RefSeq, Jul 2008]

Ambry Genetics

Mar 14, 2023

The c.1265C>T (p.P422L) alteration is located in exon 11 (coding exon 10) of the CCNK gene. This alteration results from a C to T substitution at nucleotide position 1265, causing the proline (P) at amino acid position 422 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
