Does COMT Play a Role in Parkinson's Disease Susceptibility across Diverse Ancestral Populations?

ABSTRACT:

Background

The catechol-O-methyltransferase (COMT) gene is involved in brain catecholamine metabolism, but its association with Parkinson's disease (PD) risk remains unclear.

Objective

Our aim was to investigate the relationship between COMT genetic variants and PD risk across diverse ancestries.

Methods

We analyzed COMT variants in 2251 PD patients and 2835 controls of European descent using whole-genome sequencing from the Accelerating Medicines Partnership-Parkinson Disease (AMP-PD), along with 20,427 PD patients and 11,837 controls from 10 ancestries using genotyping data from the Global Parkinson's Genetics Program (GP2).

Results

Using the largest case-control datasets to date, no significant enrichment of COMT risk alleles in PD patients was observed acro
