To test the possible effect of genetic variation in DNM3 on age at onset in idiopathic PD, we examined rs2421947 in a total of 5918 patients with PD from seven data sets.
Recently, rs2421947 in DNM3 (dynamin 3) was reported as a genetic modifier of age at onset (AAO) of LRRK2 G2019S-related Parkinson's disease (PD) in a genome-wide association study in Arab-Berber population.
A recent study showed that Arab-Berbers GG homozygous at rs2421947(C/G) in the dynamin 3 gene (DNM3) had 12.5 years earlier age at onset of leucine-rich repeat kinase 2 (LRRK2)-associated Parkinson's disease (PD) (L2PD).
