[Function study advances of Parkinson disease related genes]

Parkinson cents disease (PD) is a common extrapyramidal disease, of which the cardinal symptoms are hypokinesia, muscular rigidity, and tremor. The main pathological characteristics of this disease are loss of dopamine neurons in substantia nigra pars compacta, and residual neurons often contain Lewy bodies. The PD pathogenesis is still not well known, while it is generally recognized that age and environmental factors participate in it. In recent years, genetic research on PD has made considerable progresses that genetic factors play important roles on the pathogenesis of PD, and multiple PD related genes, such as SNCA, LRRK2, PINK1, parkin, UCHL1, and DJ1, have been identified. This article summarizes recent progresses on these genes to provide reference for PD study.
