Retrospective analysis finds increased rare variant burden in mitochondrial metabolism genes in early-onset and familial Parkinson’s disease, indicating potential genetic links.
Key Points
This research investigates the role of rare genetic variants in mitochondrial metabolism genes in early-onset and familial Parkinson's disease.
Conducted a retrospective analysis of 248 patients with early-onset or familial PD and 1622 controls.
Assessed pathway-level and gene-level burden of rare variants through exome sequencing.
Analyzed mutation burden in 467 nuclear genes associated with mitochondrial metabolism.
Gene-set mutation burden analysis showed an increased burden in genes related to mtDNA maintenance.
Identified potential associations between PD and rare variant burden in 14 mitochondrial metabolism genes under both dominant and recessive inheritance models.
