  • Description: <jats:title>Abstract</jats:title><jats:sec><jats:title>Background</jats:title><jats:p>Mutations in the gene glucocerebrosidase (<jats:italic>GBA1</jats:italic>) are specifically associated with alpha‐synucleinopathies, namely, Parkinson's disease (PD) and dementia with Lewy bodies. As disease‐modifying treatment options such as alpha‐synuclein lowering compounds are under way, patient stratification according to alpha‐synuclein‐specific enrichment strategies, possibly reflected by cerebrospinal fluid (CSF) profiles, is a much needed prerequisite.</jats:p></jats:sec><jats:sec><jats:title>Objective</jats:title><jats:p>Are <jats:italic>GBA1</jats:italic> mutations associated with a CSF alpha‐synuclein profile in PD?</jats:p></jats:sec><jats:sec><jats:title>Methods</jats:title><jats:p>Screening of the <jats:italic>GBA1</jats:italic> gene and analysis of CSF levels of total alpha‐synuclein were performed in 80 PD<jats:sub>GBA</jats:sub>, 80 PD<jats:sub>GBA</jats:sub>_<jats:sub>wildtype</jats:sub> and 39 healthy controls cross‐sectionally.
