Ectrodactyly, ectodermal dysplasia, and cleft lip syndrome. Case report
Summary
This study details five sporadic cases of Ectrodactyly, Ectodermal Dysplasia, and Cleft Lip (EEC) syndrome in Japan. Findings highlight hand deformities and palate clefts as common features, with some patients experiencing genitourinary anomalies or intellectual disability.
Area of Science:
- Medical Genetics
- Clinical Dysmorphology
Background:
- Ectrodactyly, Ectodermal Dysplasia, and Cleft Lip (EEC) syndrome is a rare disorder.
- Limited documentation exists regarding inherited EEC syndrome cases in Japan.
Observation:
- Five sporadic cases of EEC syndrome were identified.
- Patients presented with a range of clinical manifestations including hand deformities, polydactyly, syndactyly, and camptodactyly.
- Four patients exhibited clefts in both the primary and secondary palate.
Findings:
- Two patients had associated genitourinary anomalies.
- One patient presented with mental retardation.
- Syndactyly was consistently observed and may be a defining feature of the syndrome.
Implications:
- This case series expands the understanding of EEC syndrome's phenotypic variability.
- Highlights the importance of comprehensive evaluation for associated anomalies in EEC syndrome patients.
- Contributes to the limited Japanese literature on EEC syndrome, aiding future genetic research and clinical diagnosis.
