Among these genes, RAB29 has attracted much attention as Rab29 was found to be in the same pathway as leucine-rich repeat kinase 2, a Ser/Thr protein kinase genetically linked with both familial (PARK8) as well as sporadic PD (5, 6, 7, 8, 9, 10, 11). This evidence concerns the gene RAB29 and Parkinson disease.
