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.

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The 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. -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The missense variant c.838G>A p.Asp280Asn in the PRKN gene has been reported previously in individuals affected with Parkinson's Disease Bardien et al., 2009; Wang et al., 2008. The variant is absent in gnomAD Exomes. This variant has been reported to the ClinVar database as Uncertain Significance.The amino acid Aspartic acid at position 280 is changed to a Asparagine changing protein sequence and it might alter its composition and physico-chemical properties. Computational evidence Polyphen - Damaging, SIFT - Tolerated and MutationTaster - Polymorphism predicts conflicting evidence on protein structure and function for this variant. The reference residue is conserved by GERP++ and PhyloP across 100 vertebrates. For these reasons, this variant has been classified as Uncertain Significance. -
