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 Likely_benign. Variant got -4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.022943914).
• BP6: Variant 3-52737656-C-T is Benign according to our data. Variant chr3-52737656-C-T is described in ClinVar as [Likely_benign]. Clinvar id is 3192065.Status of the report is criteria_provided_single_submitter, 1 stars.

Ambry Genetics

Sep 01, 2021

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
