Genes affected

NDC80 (HGNC:16909): (NDC80 kinetochore complex component) This gene encodes a component of the NDC80 kinetochore complex. The encoded protein consists of an N-terminal microtubule binding domain and a C-terminal coiled-coiled domain that interacts with other components of the complex. This protein functions to organize and stabilize microtubule-kinetochore interactions and is required for proper chromosome segregation. [provided by RefSeq, Oct 2011]

Ambry Genetics

Dec 18, 2023

The c.1064T>C (p.I355T) alteration is located in exon 11 (coding exon 10) of the NDC80 gene. This alteration results from a T to C substitution at nucleotide position 1064, causing the isoleucine (I) at amino acid position 355 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
