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.

Autosomal recessive juvenile Parkinson disease 2 Uncertain:2
Uncertain significance, criteria provided, single submitterclinical testingNeuberg Centre For Genomic Medicine, NCGMMay 20, 2023The missense variant c.838G>A(p.Asp280Asn) in the PRKN gene has been reported previously in heterozygous and compound heterozygous state in individuals affected with Parkinson's Disease (Bardien et al., 2009; Wang et al., 2008). The variant is novel (not in any individuals) in gnomAD Exomes and 1000 Genomes. This variant has been reported to the ClinVar database as Uncertain Significance. The amino acid Glutamic acid at position 1161 is changed to a Alanine changing protein sequence and it might alter its composition and physico- chemical properties. The residue is conserved by GERP++ and PhyloP across 100 vertebrates. For these reasons, this variant has been classified as Uncertain Significance. In the absence of another reportable variant, the molecular diagnosis is not confirmed. -
Uncertain significance, criteria provided, single submitterclinical testingIllumina Laboratory Services, IlluminaDec 07, 2018The PARK2 c.838G>A (p.Asp280Asn) missense variant gene has been reported in one study and in a compound heterozygous state with a missense variant in one individual affected with early onset Parkinson disease (PD) (Wang et al. 2008). The p.Asp280Asn variant has also been reported in a heterozygous state in several individuals affected with PD (Oliveira et al. 2003; Clark et al. 2006; Bardien et al. 2009; Grunewald et al. 2013). The p.Asp280Asn variant was absent from 500 healthy controls and is reported at a frequency of 0.001047 in the South Asian population of the Genome Aggregation Database, which includes one homozygote (Oliveira et al., 2003; Bardien et al., 2009). Based on the limited evidence, the p.Asp280Asn variant is classified as a variant of unknown significance but suspicious for pathogenicity for juvenile Parkinson disease. This variant was observed by ICSL as part of a predisposition screen in an ostensibly healthy population. -
