Interestingly, in a study by Yılmaz et al. (2016), hsa-miR-4671-3p, hsa-miR-335-3p, hsa-miR-561-3p, hsa-miR-579-3p, and hsa-miR-3143 were found to be differentially expressed in the whole blood of PD patients and these miRNAs were found to be targeting LRRK2 gene. This evidence concerns the gene LRRK2 and Parkinson disease.
