摘要
目的 探讨心脏正常发育相关基因改变导致法洛四联症(TOF)的发生机制.方法 通过聚合酶链反应,并结合DNA测序分析方法检测散发106例TOF患者ZFPM2/FOG2基因编码区的突变或单核苷酸多态性位点.结果 在16例不同的患者ZFPM2/FOG2基因的外显子2、6、8上,分别发现多个位点基因改变,并将新发现的基因改变位点在110名健康人中进行验证,证实其改变位点均为突变位点.结论 ZFPM2/FOG2基因新位点的突变可能通过不同的机制进一步导致转录蛋白的改变,推测是法洛四联症发病的重要遗传基础.
Objective To study the change of heart normal development related genes resulting in Tetral- ogy of Fallot. Methods The polymerase chain reaction and DNA sequencing analysis method were used to detect ZFPM2/FOG2 genetic code of the mutation or a single nucleotide polymorphisms (SNPS) in sporadic 106 cases of patients with Tetralogy of Fallot. Results The results showed that in 16 cases of patients the ZFPM2/FOG2 gene changed in exon 2, 6, 8 and the new gene change sites were proved in 110 healthy persons. And those sites were proved as mutations. Conclusion FOG2 gene mutations may through the new site of different mechanisms of further led to the change of transcription protein, presumably, the onset of Tetralogy of Fallot important genetic basis.
