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]

Dec 20, 2021

The c.164C>T (p.S55L) alteration is located in exon 3 (coding exon 2) of the NDC80 gene. This alteration results from a C to T substitution at nucleotide position 164, causing the serine (S) at amino acid position 55 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
