NEK3

Chr 13

NIMA related kinase 3

Also known as: HSPK36

NEK3 encodes a serine/threonine protein kinase that regulates neuronal morphogenesis and polarity by controlling microtubule acetylation and is activated by prolactin signaling to phosphorylate VAV2 and paxillin. The gene shows extremely high constraint against loss-of-function variants, but no Mendelian diseases have been definitively associated with NEK3 mutations in current clinical databases.

This gene has evidence for multiple mechanisms of pathogenicity (gain-of-function and dominant-negative). Both the Badonyi & Marsh prediction and the broader genomic evidence point to gain-of-function as the predominant mechanism. Different variants in this gene may act through different mechanisms — interpret in context of the specific variant.

GOFprediction above median
DNprediction above median

Note: In-silico variant effect predictors (SIFT, PolyPhen, REVEL, CADD) may underestimate pathogenicity of missense variants in genes with GOF or DN mechanisms. Consider functional evidence and clinical context.
