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.

Variant summary: PRKN c.1310C>T (p.Pro437Leu) results in a non-conservative amino acid change located in the IBR domain (IPR002867) of the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 0.0027 in 1613282 control chromosomes in the gnomAD database, including 9 homozygotes. c.1310C>T has been reported in the literature in individuals affected Parkinson disease/early onset PD (examples: Milanowski_2021, Castelo_2021, Lesage_2020, Pankratz_2009). These data do not allow any conclusion about variant significance. Functional studies have shown a damaging effect for P437L with reduced binding ability and ubiquitination activity of parkin (examples: Sriram_2005, Yi_2019) The following publications have been ascertained in the context of this evaluation (PMID: 30994895, 16049031, 33845304, 34434164, 33045815, 19636047). ClinVar contains an entry for this variant (Variation ID: 283504). Based on the evidence outlined above, the variant was classified as uncertain significance. -

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases was too high to be consistent with this variant causing disease. Therefore, this variant is classified as benign. -
