Genes affected

CCNC (HGNC:1581): (cyclin C) The protein encoded by this gene is a member of the cyclin family of proteins. The encoded protein interacts with cyclin-dependent kinase 8 and induces the phophorylation of the carboxy-terminal domain of the large subunit of RNA polymerase II. The level of mRNAs for this gene peaks in the G1 phase of the cell cycle. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

The c.218A>G (p.Y73C) alteration is located in exon 3 (coding exon 3) of the CCNC gene. This alteration results from a A to G substitution at nucleotide position 218, causing the tyrosine (Y) at amino acid position 73 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
