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]

ACMG classification

Verdict is Uncertain_significance. Variant got 2 ACMG points.

The c.2153T>C (p.L718P) alteration is located in exon 14 (coding exon 14) of the NEK4 gene. This alteration results from a T to C substitution at nucleotide position 2153, causing the leucine (L) at amino acid position 718 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
