Genes affected
CLP1 (HGNC:16999): (cleavage factor polyribonucleotide kinase subunit 1) This gene encodes a member of the Clp1 family. The encoded protein is a multifunctional kinase which is a component of the tRNA splicing endonuclease complex and a component of the pre-mRNA cleavage complex II. This protein is implicated in tRNA, mRNA, and siRNA maturation. Mutations in this gene are associated with pontocerebellar hypoplasia type 10 (PCH10). Alternatively splice transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2014]

This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 78 of the CLP1 protein (p.Arg78Cys). This variant is present in population databases (rs374658636, gnomAD 0.08%), and has an allele count higher than expected for a pathogenic variant. 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. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt CLP1 protein function. ClinVar contains an entry for this variant (Variation ID: 1446127). This variant has not been reported in the literature in individuals affected with CLP1-related conditions. -
