The multilevel data generation of the Luxembourg Parkinson’s study has so far provided large-scale genotyping (NeuroChip (69), targeted re-sequencing of GBA1 gene via PacBio (70) and whole genome sequencing), whole-blood miRNA microarray data, 16S metagenomic data for the gut microbiome, functional models using induced pluripotent stem cells (iPSCs), digital tools / sensor data and brain bank with neuropathological evaluation that continues to contribute to the research field of PD and related disorders. This evidence concerns the gene GBA1 and Parkinson disease.
