Genes affected

VRK1 (HGNC:12718): (VRK serine/threonine kinase 1) This gene encodes a member of the vaccinia-related kinase (VRK) family of serine/threonine protein kinases. This gene is widely expressed in human tissues and has increased expression in actively dividing cells, such as those in testis, thymus, fetal liver, and carcinomas. Its protein localizes to the nucleus and has been shown to promote the stability and nuclear accumulation of a transcriptionally active p53 molecule and, in vitro, to phosphorylate Thr18 of p53 and reduce p53 ubiquitination. This gene, therefore, may regulate cell proliferation. This protein also phosphorylates histone, casein, and the transcription factors ATF2 (activating transcription factor 2) and c-JUN.

Likely pathogenic, criteria provided, single submitter	clinical testing	Baylor Genetics	Jan 27, 2014	Likely pathogenicity based on finding it once in our laboratory in trans with another missense variant [R321C] in a 33-year-old male with clinical diagnoses of distal spinal muscular atrophy and motor neuropathy. -
Pathogenic, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Feb 16, 2024	This sequence change replaces histidine, which is basic and polar, with arginine, which is basic and polar, at codon 119 of the VRK1 protein (p.His119Arg). This variant is present in population databases (rs371295780, gnomAD 0.01%). This missense change has been observed in individual(s) with adult onset distal spinal muscular atrophy (PMID: 26583493, 27281532). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 209204). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. Experimental studies have shown that this missense change affects VRK1 function (PMID: 31527692). For these reasons, this variant has been classified as Pathogenic. -
