Abstract
Four recent papers related specifically to the familial form of Parkinson's disease reinforce the idea that endogenous levels of α-synuclein can strongly influence disease phenotype. Two recent publications of α-synuclein-duplication mutations show that the severity of familial Parkinsonian phenotype is dependent upon SNCA gene dosage and corresponding protein levels. Familial point mutations in SNCA were found to impair the efficient lysosomal degradation of α-synuclein, potentially resulting in elevated levels of α-synuclein. Conversely, the complete knockout of SNCA has little effect on transgenic mice. It is now clear that the regulation of α-synuclein levels has potential significance in the pathogenesis and treatment of sporadic PD.
