Parkinson disease is an idiopathic disorder of the extra pyramidal system characterized by tremors. Genetic factors contribute to its complex pathogenesis. A functional repeat polymorphism in the α-synuclein (SNCA) gene promoter conveys susceptibility for Parkinson disease. The α-synuclein (SNCA) has been implicated in rare autosomal dominant forms of Parkinson disease. The mutations in α-synuclein were associated with severe disease progression and a typical physical signs, indicative of neuro degeneration extending beyond the substantia nigra. Mutation in α-synuclein gene may have association with dopaminergic neuronal loss in Parkinson disease. Blood samples were collected from Parkinson disease patients. DNA was extracted by organic method. Primers were designed using Primer3 software. Amplification of gene was done by Polymerase Chain Reaction. PCR products were sequenced bi-directionally on ABI 3130XL Genetic analyzer. Sequence alignment was performed for polymorphism identification. The analysis of identified polymorphism has been done by CHROMAS software. Sequences were aligned by BLAST tool of NCBI. The results of analysis showed that no mutation found in exonic region of α-synuclein (SNCA) gene in Pakistani individuals selected for this study. Any change in exonic region of α-synuclein (SNCA) gene is a rare cause of sporadic and familial Parkinson disease in different populations.
