Genes affected

ZW10 (HGNC:13194): (zw10 kinetochore protein) This gene encodes a protein that is one of many involved in mechanisms to ensure proper chromosome segregation during cell division. This protein is an essential component of the mitotic checkpoint, which prevents cells from prematurely exiting mitosis. [provided by RefSeq, Aug 2011]

The c.1490C>G (p.A497G) alteration is located in exon 10 (coding exon 10) of the ZW10 gene. This alteration results from a C to G substitution at nucleotide position 1490, causing the alanine (A) at amino acid position 497 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
