摘要 目的建立应用SYBR Green I实时荧光定量聚合酶链反应(Real—time PCR,RT—PCR)检测parkin基因外显子重排突变的技术平台,应用该技术对常染色体隐性遗传早发型帕金森综合征(autosomal recessive early—onset parkinsonism,AREP)家系进行parkin基因外显子重排突变分析。方法应用SYBR Green I RT—PCR技术对32个中国AREP家系进行parkin基因外显子重排突变分析。结果14个家系先证者存在parkin基因外显子重排突变,其中3个为纯合缺失突变、3个为复杂杂合缺失突变和8个杂合缺失突变,未发现外显子重复突变,突变主要累及第2~4号外显子。结论建立了应用SYBR Green IRT-PCR技术检测parkin基因外显子重排突变的基因检测平台;中国AREP家系的parkin基因外显子重排突变频率为43.8%,与国外报道相似。 Objective To develop a method of detection exon rearrangements in the parkin gene (PARK2) using SYBR Green I real-time PCR and to analyze PARK2 exon rearrangement mutations in families with autosomal recessive early-onset parkinsonism (AREP) using this method. Methods Exon rearrangement in PARK2 was screened by SYBR Green I real-time PCR in 32 families with AREP. Results Exon rearrangement mutations were found in 14 families, including 3 compound heterozygous deletions; 3 homozygous deletions; and 8 heterozygous deletions. No duplication mutation was found. Hotspot for exon rearrangements clustered in exons 2 through 4. Conclusions We have developed a gene test method using SYBR Green I Real-time PCR to detect exon rearrangements in the gene PARK2. The frequency of PARK2 mutation is 43.8% in Chinese families with AREP. This frequency is similar to reported findings in other countries.
