Ankyloblepharon-ectodermal dysplasia-clefting (AEC) syndrome is a rare disorder characterized by ankyloblepharon (congenital adhesions of the eyelids), ectodermal dysplasia, and orofacial clefts. Here, we report the case of an infant born with severe ectodermal dysplasia including generalized neonatal erosions with scalp involvement, facial clefting but notably without ankyloblepharon. Mutational analysis of the p63 gene showed a novel heterozygous T>C nucleotide substitution on exon 14 (I597T). To our knowledge, this is a novel mutation that has not previously been reported in the pathogenesis of AEC, or other p63-related syndromes. This case further highlights the clinical and genetic heterogeneity of p63 syndromes.
睑缘粘连-外胚层发育不良-腭裂(AEC)综合征是一种罕见的疾病,其特征为睑缘粘连(先天性眼睑粘连)、外胚层发育不良和口面部裂隙。在此,我们报告一例出生时患有严重外胚层发育不良的婴儿病例,包括累及头皮的全身性新生儿糜烂、面部裂隙,但值得注意的是无睑缘粘连。p63基因的突变分析显示外显子14上有一个新的杂合T>C核苷酸替换(I597T)。据我们所知,这是一种新的突变,此前在AEC或其他p63相关综合征的发病机制中尚未有报道。该病例进一步凸显了p63综合征的临床和遗传异质性。
