ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the relationship between idiopathic Parkinson's disease (PD) and two polymorphisms (C243G and A377T) of the gamma-synuclein gene in a Chinese Han population of Shanghai area.</p><p><b>METHODS</b>Polymorphic genotyping was performed with PCR-RPLP technique. Association analysis was carried out in 145 unrelated idiopathic PD patients and 184 age-matched healthy controls.</p><p><b>RESULTS</b>The authors failed to detect any distributional difference of the C243G and A377T polymorphisms of the gamma-synuclein gene between PD cases and control subjects, nor did they find any association.</p><p><b>CONCLUSION</b>These data do not support that gamma-synuclein gene C243G and A377T polymorphisms are involved in idiopathic PD onset in the Han population of Shanghai area.</p>
