嗜铬细胞瘤7个致病基因的高通量基因检测方法的建立

Establishment of a high throughput gene detection method for seven pathogenic genes of pheochromocytoma

目的·建立嗜铬细胞瘤致病基因的高通量测序检测方法平台体系,为基因诊断进入常规临床检测作准备。方法·采用高通量测序建库两步PCR方法,针对嗜铬细胞瘤的7个致病基因(SDHB,SDHC,SDHD,VHL,MAX,TMEM127和RET)的35个基因片段进行建库,然后使用Miseq机器进行后续的高通量测序。结果·建库的35个基因片段在Miseq机器都得到了检测,并且均一性达到了实验最初的设想。结论·该实验方法完成了嗜铬细胞瘤7个致病基因的基因检测工作,实验的质量和成本都达到了预期效果。

Objective · To establish a test method platform system for high throughput sequencing of pathogenic genes of pheochromocytoma and make preparation for including the genetic diagnosis into routine clinical testing. Methods · The bank was constructed for 35 DNA fragments in 7 pathogenic genes （SDHB, SDHC, SDHD, VHL, MAX, TMEM127, and RET） of pheochromocytoma with two-step PCR method of high throughput sequencing. The high throughput sequencing was performed on illumine Miseq machine. Results · Thirty-five DNA fragments were detected on illumine Miseq machine and the uniformity met the design of experiment. Conclusion · This method completed the gene detection for 7 pathogenic genes of pheochromocytoma. The quality and cost of the experiment achieved the expectation.
