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]

ACMG classification

Verdict is Uncertain_significance. Variant got 3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.761

Collection Method: clinical testing

The c.2095C>T (p.P699S) alteration is located in exon 15 (coding exon 15) of the ZW10 gene. This alteration results from a C to T substitution at nucleotide position 2095, causing the proline (P) at amino acid position 699 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
