Since then, a number of mutations in genes for PTEN-induced putative kinase 1 (PINK1), Parkinson protein 2 (PARK2), Parkinson protein 7 (parkk7/DJ-1), Leucin-rich repeat kinase 1 (LRRK1) and others have been shown to induce Parkinson’s disease symptoms, mostly early onset and indistinguishable from sporadic cases [19, 20] (reviewed in [21]). The gene discussed is PINK1; the disease is Parkinson disease.
