Genes affected

CDC20 (HGNC:1723): (cell division cycle 20) CDC20 appears to act as a regulatory protein interacting with several other proteins at multiple points in the cell cycle. It is required for two microtubule-dependent processes, nuclear movement prior to anaphase and chromosome separation. [provided by RefSeq, Jul 2008]

The c.1018C>A (p.P340T) alteration is located in exon 8 (coding exon 7) of the CDC20 gene. This alteration results from a C to A substitution at nucleotide position 1018, causing the proline (P) at amino acid position 340 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
