Congenital hypothyroidism (CH), attributable to thyroid dysgenesis (TD), has an unusually high prevalence in Mexican population but the causes are unknown. , as a candidate gene, was subjected to automated Sanger sequencing in 122 unrelated Mexican patients with CH/TD. Although this study includes the largest number of TD-related CH patients in whom has been analyzed, no pathogenic variants were detected; only three benign polymorphic changes were identified. These results suggest that is not a major contributor to the etiology of CH or its high prevalence in Mexicans. Our work identifies misannotations of variants in three previous published reports.
先天性甲状腺功能减退症(CH),归因于甲状腺发育不全(TD),在墨西哥人群中患病率异常高,但病因不明。作为候选基因,对122名无关的墨西哥CH/TD患者进行了自动桑格测序。尽管本研究纳入了分析该基因的与TD相关的CH患者数量最多的队列,但未检测到致病变异;仅鉴定出三个良性多态性变化。这些结果表明,该基因不是CH病因或其在墨西哥人高患病率的主要促成因素。我们的工作识别出了之前三篇已发表报告中该基因变异的错误注释。
