MAPT and Parkinson disease: To investigate further the role of lncRNAs in PD pathogenesis, we have identified seven human lncRNA genes producing transcripts in close genomic proximity to PD-related genes, including SNCA (PARK4), LRRK2 (PARK8), UCH-L1 (PARK5), PINK1 (PARK6), DJ-1 (PARK7), GBA1, and MAPT. These lncRNA genes have been formerly annotated by human genome consortia (ENCODE and FANTOM) and are thought to be potentially expressed in human cells.
