RESUMEN

<p><b>OBJECTIVE</b>To explore whether there are gene mutations of Tolloid-like 1 (TLL-1) gene in Chinese patients with sporadic congenital heart disease (CHD).</p><p><b>METHODS</b>One hundred and fifteen patients with sporadic CHD were selected as CHD group. One hundred and two age and gender-matched healthy people were recruited as control group. After amplifying the exon 10 of the TLL-1 gene by polymerase chain reaction, the polymerase chain reaction products were purified, sequenced and analyzed in order to investigate the TLL-1 gene mutation.</p><p><b>RESULTS</b>An insertion mutation of base A in the exon 10 of TLL-1 gene was identified in 7 out of 115 CHD patients, including 3 patients with atrial septal defect, 2 patients with ventricular septal defect, 1 patients with patent ductus arteriosus and 1 patients with complex CHD, the total mutation rate was 6.1% in CHD group and 0 in control group (P < 0.01).</p><p><b>CONCLUSIONS</b>TLL-1 gene mutation with an insertion mutation of base A in exon 10 is often in Chinese patients with various CHD. The underlying pathogenesis between TLL-1 gene mutation and occurrence of congenital heart disease in Chinese people remains unclear and warrants further investigations.</p>
