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.

Pontocerebellar hypoplasia type 1A Uncertain:2
Uncertain significance, criteria provided, single submitterclinical testingInvitaeMay 25, 2022This sequence change replaces glutamine, which is neutral and polar, with arginine, which is basic and polar, at codon 45 of the VRK1 protein (p.Gln45Arg). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with VRK1-related conditions. ClinVar contains an entry for this variant (Variation ID: 533536). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
