Increases in the number of allelic malformation syndromes have led to their classification according to their pathogenesis rather than their clinical specific phenotype. TP63 (also known as TP73L) mutations have been identified in several such syndromes characterized by autosomal dominant transmission and various combinations of ectodermal dysplasia, limb malformations and orofacial clefting. TP63 has not yet been implicated in early aging phenotype in humans, even though p63 activates a program of cellular senescence and p63-compromised mice display features of accelerated aging. We report on a family with four affected adult females presenting with Rapp-Hodgkin syndrome (RHS), an autosomal dominant clinical entity that associates anhidrotic ectodermal dysplasia with cleft lip and palate. Features between RHS and EEC syndrome (ectrodactyly, ectodermal dysplasia and cleft lip/palate) have led to the recent identification of mutations in the TP63 gene, located on 3q27, in this condition. Our patients present typical clinical features of RHS, but also ophthalmic anomalies such as corneal dystrophy and premature menopause (around 30 years). The latter findings have never been reported in this condition, and could be secondary to a new TP63 deletion that has been identified in this family.

:等位基因畸形综合征数量的增加已导致根据其发病机理而不是根据临床特定表型对它们进行分类。 TP63(也称为TP73L)突变已在几种以常染色体显性遗传和外胚层发育不良,肢体畸形和口唇裂的各种组合为特征的综合症中得到鉴定。 TP63尚未涉及人类的早期衰老表型,即使p63激活了细胞衰老程序并且p63受损的小鼠也表现出加速衰老的特征。我们报告了一个家庭,该家庭有四名受影响的成年女性,表现出拉普霍奇金综合征(RHS),这是一种常染色体显性临床实体,将无角质外胚层发育不良与唇left裂相关。 RHS和EEC综合征之间的特征(实际上是外胚层发育异常和唇裂/唇pal裂)导致这种情况下最近鉴定出位于3q27的TP63基因突变。我们的患者表现出RHS的典型临床特征,还表现出眼科异常,例如角膜营养不良和更年期提前(约30年)。后者的发现从未在这种情况下报道过,可能是该家族中已发现的新的TP63缺失的继发者。
