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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 03, 2023The c.940A>G (p.M314V) alteration is located in exon 10 (coding exon 9) of the NDC80 gene. This alteration results from a A to G substitution at nucleotide position 940, causing the methionine (M) at amino acid position 314 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
