Objective:
To elucidate the genetic risk and role of alpha-synuclein gene in the pathogenesis of Parkinson's disease in Pakistani population.
Methods:
This case-control study was conducted at Institute of Biomedical and Genetic Engineering (IBGE), Islamabad from May 2013 to May 2016, and comprised patients with Parkinson's disease and their ethnically-matched healthy controls. Allele-specific polymerase chain reaction was used for screening of three pathogenic single nucleotide polymorphisms in alpha-synuclein gene. Moreover, 20% samples were randomly selected for bidirectional Sanger sequencing to confirm the results. SPSS 13 was used for data analysis.
Results:
Of the 374 participants, 174(46.5%) were patients and 200(53.5%) were controls. The mean age for the onset of the disease was 55±13 years. No polymorphism was observed for rs104893875(G>A), rs104893877(G>A) and rs104893878(C>G) in alpha-synuclein gene in samples of patients and controls.
Conclusions:
Alpha-synuclein gene mutations might not be relevant to all the populations in causing Parkinson's disease.

Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...
