Genes affected

PRKN (HGNC:8607): (parkin RBR E3 ubiquitin protein ligase) The precise function of this gene is unknown; however, the encoded protein is a component of a multiprotein E3 ubiquitin ligase complex that mediates the targeting of substrate proteins for proteasomal degradation. Mutations in this gene are known to cause Parkinson disease and autosomal recessive juvenile Parkinson disease. Alternative splicing of this gene produces multiple transcript variants encoding distinct isoforms. Additional splice variants of this gene have been described but currently lack transcript support.

This sequence change replaces valine, which is neutral and non-polar, with glutamic acid, which is acidic and polar, at codon 56 of the PRKN protein (p.Val56Glu). This variant is present in population databases (rs137853059, gnomAD 0.01%). This missense change has been observed in individual(s) with early-onset Parkinson disease (PMID: 12056932). 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: 7047). 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) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on PRKN protein function. Experimental studies have shown that this missense change affects PRKN function (PMID: 15606901, 30994895). For these reasons, this variant has been classified as Pathogenic. -
