In particular, MRC Holland (Netherlands) offers a set of SALSA MLPA P051-C2, which includes reagents for detecting mutations in the genes of the main proteins involved in the etiopathogenesis of Parkinson’s disease: the protein genes SNCA (alpha-synuclein), PARK2 (parkin), LRRK2 (dardarin), and PINK1. This panel allows studying polymorphisms in candidate genes, presumptively determining the risk of developing PD (SNCA, MAPT) [83,84]. The gene discussed is LRRK2; the disease is Parkinson disease.
