ABSTRACT
<p><b>OBJECTIVE</b>To identify thyroid peroxidase (TPO) gene mutations in 35 patients with congenital hypothyroidism.</p><p><b>METHOD</b>Genomic DNA was isolated from peripheral blood samples of 35 patients with congenital hypothyroidism. All of the 17 exons and flanking introns of TPO gene were amplified by PCR, then the PCR products were sequenced bi-directionally and were analyzed by restriction endonucleases.</p><p><b>RESULT</b>One patient had compound heterozygous mutations c.961A>G/c.2422delT, one was c.2268insT/c.1477G>A, and three was homozygous mutation c.2268insT. The TPO gene mutation c.961A>G [p. Thr321Ala] was one novel mutation.</p><p><b>CONCLUSION</b>High frequency mutation in TPO gene was detected in patients with congenital hypothyroidism.</p>
