PARKIN, PINK1, and DJ1 analysis in early-onset Parkinson's disease in Ireland.

ABSTRACT:

Background

Variants in PARKIN, PINK1, and DJ1 are associated with early-onset Parkinson' disease (EOPD, age-at-onset < 45). We previously reported a single PINK1 and a single DJ1 heterozygous variant carrier.

Purpose

We aimed to expand upon our previous EOPD studies and investigate for any genotype-phenotype correlations in Irish PD.

Methods

Three hundred fourteen PD patients were recruited from Dublin Neurological Institute, Ireland. Genetic analysis was performed at the Mayo Clinic, Jacksonville, USA. We screened 81 patients with young-onset PD (age-at-onset < 50), of which 58 had EOPD.

Results

We identified 4 patients with homozygous/compound heterozygous variants and 3 heterozygote carriers (pathogenic PINK1/DJ1 variants were not found). Expansion of one of
