OBJECTIVE: To investigate the value of fluorescence semi-quantitative PCR in analysis of the exon rearrangement of parkin gene in Chinese patients with isolated early-onset parkinsonism (EOP). METHODS: fluorescence semi-quantitative PCR was used to analyze the exon rearrangements of parkin gene in 61 isolated patients with EOP. RESULTS: Exon deletions in parkin gene were found in 4 of the 61 isolated patients with EOP. One of them failed to show the PCR product of exon 4 and had homozygous deletions of exon 4. The normalized ratios (NRs) of exon 2, exon 3, and exon 4 of the other 3 patients were 0.47, 0.52, and 0.49 respectively, showing that they had heterozygous deletions of exon 2, 3, and 4 respectively. No exon multiplication was found in this study. CONCLUSION: Exon rearrangement of parkin gene exists in Chinese patients with isolated EOP.
