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]

Ambry Genetics

Jun 01, 2023

The c.517G>C (p.D173H) alteration is located in exon 5 (coding exon 4) of the CDC20 gene. This alteration results from a G to C substitution at nucleotide position 517, causing the aspartic acid (D) at amino acid position 173 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
