The genetic architecture of Parkinson's disease in Mexico: a systematic review

This systematic review provides the first quality-assessed synthesis of genetic studies of Parkinson's disease conducted in Mexico. The available evidence supports the involvement of established Parkinson's disease-related molecular pathways while underscoring substantial methodological heterogeneity and limited ancestry-aware analyses. Larger, well-powered genome-wide and multi-omic studies incorporating explicit ancestry modeling are required to refine genetic risk architecture and improve the interpretability of Parkinson's disease genomics in Mexican populations.
