RCV000792141 | SCV000931419 | pathogenic | Autosomal recessive juvenile Parkinson disease 2 | 2018-08-06 | criteria provided, single submitter | clinical testing | This variant results in a copy number gain of the genomic region encompassing exon 7 of the PARK2 gene. While the exact position of this variant cannot be determined from this data, sub-genic copy number gains are generally in tandem (PMID: 25640679) and may result in an absent or disrupted protein product. Similar copy number gains of exon 7 have been observed in combination with or on the opposite chromosome (in trans) from other pathogenic variants in individuals and families affected with early-onset Parkinson’s disease (PMID: 11889248, 21993715), and have also been observed to segregate with disease in affected families (PMID: 21993715). Loss-of-function variants in PARK2 are known to be pathogenic (PMID: 10072423, 20301651, 22956510). For these reasons, this variant has been classified as Pathogenic. |
