Abstract
目的:探讨McCune-Albright综合征患儿的临床特点及基因突变,并复习相关文献.方法:分析本院收治的2例McCune-Albright综合征患儿的临床资料,并收集其新鲜组织、外周血进行基因检测.结果:患儿主要表现为外周性性早熟(乳房发育、月经初潮、卵巢囊肿)、皮肤牛奶咖啡斑(皮肤不对称性咖啡色色素沉着,边缘不规则)、骨纤维结构不良(桡骨和/或胫腓骨远端骨质改变),基因分子遗传学分析结果显示均存在GNAS基因突变[c.602G>A杂合突变(p.R201H)、c.46C>T(p.R16C)].结论:McCune-Albright综合征临床罕见,容易漏诊及误诊,基因检测分析有助于McCune-Albright综合征患儿的临床诊断.
