Genes affected

CDC25B (HGNC:1726): (cell division cycle 25B) CDC25B is a member of the CDC25 family of phosphatases. CDC25B activates the cyclin dependent kinase CDC2 by removing two phosphate groups and it is required for entry into mitosis. CDC25B shuttles between the nucleus and the cytoplasm due to nuclear localization and nuclear export signals. The protein is nuclear in the M and G1 phases of the cell cycle and moves to the cytoplasm during S and G2. CDC25B has oncogenic properties, although its role in tumor formation has not been determined. Multiple transcript variants for this gene exist. [provided by RefSeq, Jul 2008]

The c.457C>A (p.P153T) alteration is located in exon 5 (coding exon 5) of the CDC25B gene. This alteration results from a C to A substitution at nucleotide position 457, causing the proline (P) at amino acid position 153 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
