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]

Jan 17, 2024

The c.778G>A (p.V260M) alteration is located in exon 9 (coding exon 8) of the NDC80 gene. This alteration results from a G to A substitution at nucleotide position 778, causing the valine (V) at amino acid position 260 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
