Recent studies have shown that PLA2G6 is a causative gene for PARK14-linked autosomal recessive early-onset complicated dystonia-parkinsonism, early-onset parkinsonism with frontotemporal dementia and autosomal recessive early-onset Parkinsonism without added complicated clinical features. In order to investigate the characteristics of PLA2G6 gene mutations in Chinese sporadic early-onset parkinsonism (FOP) patients, we performed polymerase chain reaction and DNA direct sequencing on a cohort of sporadic EOP patients from Chinese population. In this study, we found a novel heterozygous varient (p.G679V). Bioinformatics demonstrates that p.G679V exhibits highly conserved residues across species, which hints it might be a pathogenic mutation. Our result indicated that PLA2G6 mutations might not be a main cause of Chinese sporadic EOP. (C) 2012 Elsevier Ireland Ltd. All rights reserved.
