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]

In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals affected with NEK2-related conditions. This variant is present in population databases (rs746603282, gnomAD 0.009%). This sequence change replaces serine, which is neutral and polar, with tyrosine, which is neutral and polar, at codon 408 of the NEK2 protein (p.Ser408Tyr). -
