Do you know anyone whose brain is challenged with PD? Parkinson’s cases now known to have genetic origins are shedding light on the cellular mechanisms of all the rest, bringing researchers closer to a cause—and perhaps a cure. This is not only interesting but also exciting! Study results have shown some compelling evidence suggesting that loss-of-function mutations rendering three genes (parkin, PINK1 and DJ-1) functionally inactive, underlie common forms of autosomal-recessive PD. Identification and characterization of familial PD-linked genes has sparked an extremely fruitful line of research, delineating molecular pathways that are involved in the pathogenesis of PD.
