Genes affected

NEK4 (HGNC:11399): (NIMA related kinase 4) The protein encoded by this gene is a serine/threonine protein kinase required for normal entry into replicative senescence. The encoded protein also is involved in cell cycle arrest in response to double-stranded DNA damage. Finally, this protein plays a role in maintaining cilium integrity, and defects in this gene have been associated with ciliopathies. [provided by RefSeq, Jan 2017]

The c.2054C>T (p.T685I) alteration is located in exon 13 (coding exon 13) of the NEK4 gene. This alteration results from a C to T substitution at nucleotide position 2054, causing the threonine (T) at amino acid position 685 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
