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 GeneticsDec 18, 2023The c.625C>A (p.Q209K) alteration is located in exon 7 (coding exon 6) of the NDC80 gene. This alteration results from a C to A substitution at nucleotide position 625, causing the glutamine (Q) at amino acid position 209 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
