Genes affected
CCNL2 (HGNC:20570): (cyclin L2) The protein encoded by this gene belongs to the cyclin family. Through its interaction with several proteins, such as RNA polymerase II, splicing factors, and cyclin-dependent kinases, this protein functions as a regulator of the pre-mRNA splicing process, as well as in inducing apoptosis by modulating the expression of apoptotic and antiapoptotic proteins. Alternatively spliced transcript variants encoding different isoforms have been described for this gene. [provided by RefSeq, Aug 2011]

The c.1258C>T (p.R420C) alteration is located in exon 11 (coding exon 11) of the CCNL2 gene. This alteration results from a C to T substitution at nucleotide position 1258, causing the arginine (R) at amino acid position 420 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
