The GBA gene encodes for the lysosomal enzyme glucocerebrosidase (GCase), which
maintains glycosphingolipid homeostasis. Approximately 5–15% of PD patients have …

Depression is one of the most important non-motor symptoms in Parkinson's disease (PD),
but its prevalence and related clinical characteristics are unclear. To this end, we performed …

Almost 2 decades after linking LRRK2 to Parkinson's disease, a vibrant research field has
developed around the study of this gene and its protein product. Recent studies have begun …

The genetic landscape of Parkinson's disease (PD) is characterised by rare high penetrance
pathogenic variants causing familial disease, genetic risk factor variants driving PD risk in a …

About 15% of patients with Parkinson disease (PD) have family history and 5–10% have a
monogenic form of the disease with Mendelian inheritance. To date, at least 23 loci and 19 …

Dementia is a frequent problem encountered in advanced stages of Parkinson disease (PD).
In recent years, research has focused on the pre-dementia stages of cognitive impairment in …

Gaucher disease (GD, ORPHA355) is a rare, autosomal recessive genetic disorder. It is
caused by a deficiency of the lysosomal enzyme, glucocerebrosidase, which leads to an …

Parkinson's disease (PD) is the second most common degenerative disorder. Although the
disease was described more than 200 years ago, its pathogenetic mechanisms have not yet …

Dementia with Lewy bodies (DLB) and Parkinson's disease-dementia (PDD), although
sharing many clinical, neurochemical and morphological features, according to DSM-5, are …

Background Common genetic variance in apolipoprotein E (APOE), β‐glucocerebrosidase
