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

Jul 20, 2021

The c.83G>A (p.G28D) alteration is located in exon 2 (coding exon 1) of the NDC80 gene. This alteration results from a G to A substitution at nucleotide position 83, causing the glycine (G) at amino acid position 28 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
