Genes affected

CCNB2 (HGNC:1580): (cyclin B2) Cyclin B2 is a member of the cyclin family, specifically the B-type cyclins. The B-type cyclins, B1 and B2, associate with p34cdc2 and are essential components of the cell cycle regulatory machinery. B1 and B2 differ in their subcellular localization. Cyclin B1 co-localizes with microtubules, whereas cyclin B2 is primarily associated with the Golgi region. Cyclin B2 also binds to transforming growth factor beta RII and thus cyclin B2/cdc2 may play a key role in transforming growth factor beta-mediated cell cycle control. [provided by RefSeq, Jul 2008]

Ambry Genetics

Dec 13, 2022

The c.876G>C (p.E292D) alteration is located in exon 7 (coding exon 7) of the CCNB2 gene. This alteration results from a G to C substitution at nucleotide position 876, causing the glutamic acid (E) at amino acid position 292 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
