摘要 目的探讨抑癌基因SDHD和MEN1的突变与杂合性缺失,在嗜铬细胞瘤(PCC)发病机制中的作用。方法采用DNA直接测序法对SDHD和MEN1基因的全部外显子及其侧翼进行分析,寻找基因突变。选用荧光标记11q13区-23区的8个多态性微卫星位点对37例PCC进行杂合性缺失频率检测。分析上述检测结果与临床资料的关系。结果在37例PCC肿瘤组织中未发现SDHD和MEN1基因突变。发现3种SDHD基因内含子改变(15519972c/g,15521745c/t,15520001c/a),2种MEN1基因内含子改变(9879384a/g,9878352C/T)。SDHD所在区域11q23的杂合性缺失频率为30.8%。MEN1所在区域11q13的杂合性缺失频率为26.9%。结论PCC中未发现SDHD和MEN1基因突变;发现一定比例的11q13区-23区域的杂合性缺失,提示在该区域可能存在其他的抑癌基因参与PCC的发病机制。
