Case report: Prenatal diagnosis of Ectrodactyly-Ectodermal dysplasia-Cleft syndrome (EEC) in a fetus with cleft lip and polycystic kidney. Front Genet 2022; 13:1002089. [PMID: 36386837 PMCID: PMC9662688 DOI: 10.3389/fgene.2022.1002089] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2022] [Accepted: 09/28/2022] [Indexed: 09/05/2023] Open
Abstract
Ectrodactyly-ectodermal dysplasia-cleft (EEC) syndrome is an autosomal dominant disorder characterized by ectrodactyly, ectodermal dysplasia, and orofacial clefting. Reduced penetrance is manifested in these core features and additional under-recognized features, especially in prenatal cases. Here, we present a fetus with EEC syndrome at 22 weeks gestation, in which the cleft lip and palate and the right polycystic kidney are shown by prenatal ultrasound. A de novo missense mutation of R304W in the TP63 gene is confirmed by whole-exome sequencing associated with EEC syndrome. We further investigate the reported TP63-related prenatal cases and provide a more complete picture of the prenatal phenotypic spectrum about EEC. It illustrates the potential severity of genitourinary anomalies in TP63-related disorders and highlights the need to counsel for the possibility of EEC syndrome, given the occurrence of genitourinary anomalies with orofacial cleft or limb deformities.

Abstract
Ectrodactyly, ectodermal dysplasia, and cleft lip/palate syndrome (EEC) syndrome is a rare genetic disorder with an incidence of around 1 in 90,000 in population. It is known with various names including split hand-split foot-ectodermal dysplasia-cleft syndrome or split hand, cleft hand, or lobster claw hand/foot. We report first case of EEC with associated heart disease (Tetralogy of Fallot) who was diagnosed as EEC on the basis of clinical features and EEC was confirmed with genetic analysis.

Abstract
Split-hand/foot malformation (SHFM) is a rare condition which can be either syndromic or nonsyndromic. We report three unrelated pedigrees, one with autosomal dominant (AD) inheritance and the other two with autosomal recessive (AR) pattern. We also briefly review the published reports from India.

Two interesting cases of EEC syndrome. J Oral Biol Craniofac Res 2013; 3:45-8. [PMID: 25737881 DOI: 10.1016/j.jobcr.2013.02.001] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2012] [Accepted: 02/06/2013] [Indexed: 11/20/2022] Open
Abstract
AIM To report two cases of EEC syndrome with oral involvement to highlight the fact that the dental surgeon may be among the first to recognise the condition. INTRODUCTION The EEC syndrome, a rare congenital syndrome is characterised by ectodermal dysplasia, distal limb anomaly, cleft lip and palate and lachrymal duct anomalies although the term oligosymptomatic EEC syndrome has been suggested for cases in which ectrodactyly may be absent and that such cases should not be deprived of the EEC syndrome diagnosis. It is usually inherited as an autosomal dominant trait with variable expressivity and penetrance and all these features rarely coexist in a single individual. CONCLUSION Both our cases had all three characteristic features of the EEC syndrome. Other syndromes with overlapping features such as the Rapp-Hodgkin syndrome and the AEC syndrome should be considered in the differential diagnosis of incomplete forms of EEC syndrome. CLINICAL SIGNIFICANCE It is important to follow an interdisciplinary approach to attain the greatest degree of success possible in the treatment of such cases.
