Genes affected

NEK2 (HGNC:7745): (NIMA related kinase 2) This gene encodes a serine/threonine-protein kinase that is involved in mitotic regulation. This protein is localized to the centrosome, and undetectable during G1 phase, but accumulates progressively throughout the S phase, reaching maximal levels in late G2 phase. Alternatively spliced transcript variants encoding different isoforms with distinct C-termini have been noted for this gene. [provided by RefSeq, Feb 2011]

Ambry Genetics

Nov 18, 2022

The c.1270G>C (p.A424P) alteration is located in exon 8 (coding exon 8) of the NEK2 gene. This alteration results from a G to C substitution at nucleotide position 1270, causing the alanine (A) at amino acid position 424 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
