Genes affected

CDCA8 (HGNC:14629): (cell division cycle associated 8) This gene encodes a component of the chromosomal passenger complex. This complex is an essential regulator of mitosis and cell division. This protein is cell-cycle regulated and is required for chromatin-induced microtubule stabilization and spindle formation. Alternate splicing results in multiple transcript variants. Pseudgenes of this gene are found on chromosomes 7, 8 and 16. [provided by RefSeq, Apr 2013]

The c.719G>A (p.R240Q) alteration is located in exon 10 (coding exon 9) of the CDCA8 gene. This alteration results from a G to A substitution at nucleotide position 719, causing the arginine (R) at amino acid position 240 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
