Genes affected

NUF2 (HGNC:14621): (NUF2 component of NDC80 kinetochore complex) This gene encodes a protein that is highly similar to yeast Nuf2, a component of a conserved protein complex associated with the centromere. Yeast Nuf2 disappears from the centromere during meiotic prophase when centromeres lose their connection to the spindle pole body, and plays a regulatory role in chromosome segregation. The encoded protein is found to be associated with centromeres of mitotic HeLa cells, which suggests that this protein is a functional homolog of yeast Nuf2. Alternatively spliced transcript variants that encode the same protein have been described. [provided by RefSeq, Jul 2008]

Nov 21, 2022

The c.91C>G (p.L31V) alteration is located in exon 2 (coding exon 1) of the NUF2 gene. This alteration results from a C to G substitution at nucleotide position 91, causing the leucine (L) at amino acid position 31 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
