最近有报道称,c-erbA β甲状腺激素受体的两种不同突变是引起全身性甲状腺激素抵抗综合征(GTHR)的遗传异常。我们现在已经在第三个家系D中发现了c-erbA β T3结合域的一个新的点突变,该家系的GTHR是一种显性遗传疾病。在10个受影响成员的一个等位基因中发现了1305位核苷酸的鸟嘌呤碱基替换为胞嘧啶碱基,将密码子335从谷氨酰胺(CAG)变为组氨酸(CAC),而在6个未受影响的成员中未发现。这个C-1305序列在106个随机等位基因中不存在,表明它是c-erbA β的突变,并且它与D家族中的GTHR紧密连锁,在重组分数为0时,最大比值分数对数为4.19。紧密连锁的结果证实,GTHR映射到c-erbA β基因座在多个激酶。鉴于C-1305突变与GTHR之间的紧密联系,并且该突变是T3结合结构域关键区域的非保守性改变,它可能是D家族中负责GTHR的遗传缺陷。亲属D受体似乎导致不同的表型的组织电阻相比,以前报道的亲属。一种在c-erbA β羧基末端发生突变的受体。
Two different mutations in the c-erbA beta thyroid hormone receptor have recently been reported as genetic abnormalities responsible for the syndrome of generalized thyroid hormone resistance (GTHR). We have now found in a third kindred, D, in which GTHR is inherited as a dominant disease, a new point mutation in the T3-binding domain of c-erbA beta. A guanine to cytosine base substitution at nucleotide position 1305, which altered codon-335 from glutamine (CAG) to histidine (CAC), was found in one allele of 10 affected members and was not found in 6 unaffected members. This C-1305 sequence was not present in 106 random alleles, indicating that it was a mutation in c-erbA beta, and it was tightly linked to GTHR in kindred D, with a maximum logarithm of the odds score of 4.19 at a recombination fraction of 0. The tight linkage result confirms that GTHR maps to the c-erbA beta locus in multiple kindreds. In view of the tight linkage between the C-1305 mutation and GTHR, and that this mutation is a nonconservative alteration in a crucial region of the T3-binding domain, it is probably the genetic defect in kindred D responsible for GTHR. The kindred D receptor appears to result in a different phenotype of tissue resistance compared to the previously reported kindred. A receptor with a mutation in the carboxy-terminus of c-erbA beta.
