Genes affected

NEK3 (HGNC:7746): (NIMA related kinase 3) This gene encodes a member of the NimA (never in mitosis A) family of serine/threonine protein kinases. The encoded protein differs from other NimA family members in that it is not cell cycle regulated and is found primarily in the cytoplasm. The kinase is activated by prolactin stimulation, leading to phosphorylation of VAV2 guanine nucleotide exchange factor, paxillin, and activation of the RAC1 GTPase. Two functional alleles for this gene have been identified in humans. The reference genome assembly (GRCh38) represents a functional allele that is associated with the inclusion of an additional coding exon in protein-coding transcripts, compared to an alternate functional allele that lacks the exon.

Ambry Genetics

Dec 19, 2023

The c.382A>G (p.I128V) alteration is located in exon 5 (coding exon 4) of the NEK3 gene. This alteration results from a A to G substitution at nucleotide position 382, causing the isoleucine (I) at amino acid position 128 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
