Analysis of the thyroid hormone receptor beta (TRbeta) gene of a Thai female with the syndrome of resistance to thyroid hormone (RTH) revealed a missense mutation at codon 317, changing the guanine in nucleotide 1234 to an adenine that results in the replacement of the normal alanine (GCT) with a threonine (ACT). The proposita was heterozygous, and this mutation was not present in her parents and her sister, compatible with a neomutation. This is the first report of TRbeta gene mutation causing RTH in an individual of Thai origin.
对一名患有甲状腺激素抵抗综合征(RTH)的泰国女性的甲状腺激素受体β(TRbeta)基因进行分析,发现第317密码子处存在错义突变,核苷酸1234中的鸟嘌呤被腺嘌呤取代,导致正常的丙氨酸(GCT)被苏氨酸(ACT)取代。先证者为杂合子,其父母和姐姐中不存在这种突变,符合新发突变。这是关于TRbeta基因突变导致泰国裔个体发生RTH的首例报告。
