Prevalence and genotype–phenotype correlations of <i>GBA</i>‐related Parkinson disease in a large Chinese cohort

Abstract

GBA-PD is highly prevalent in the Chinese population. The severity of GBA variants underlies distinct phenotypic spectrums, with PD patients carrying severe and complex variants seeming to have similar phenotypes. PD patient stratification by GBA variant severity should become a prerequisite for selecting specific treatments.
