At the moment, four genes are known, clearly implicated in autosomal dominant Parkinson’s disease—the SNCA/PARK1–PARK4 gene, the LRRK2/PARK8 gene, the VPS35/PARK17 gene, and the EIF4G1/PARK18 gene; instead, PARK-1 and DJ-1 genes are involved in the autosomal recessive transmission disease. The gene discussed is LRRK2; the disease is infectious disease.
