Ankyloblepharon-ectodermal defects-cleft lip/palate syndrome

Ankyloblepharon-ectodermal defects-cleft lip/palate (AEC) syndrome, also known as Hay-Wells syndrome, is a rare genetic disorder belonging to the group of ectodermal dysplasias caused by mutations in the TP63 gene. It is characterized by a distinctive triad of features: ankyloblepharon filiforme adnatum (thin strands of tissue connecting the upper and lower eyelids at birth), ectodermal defects, and cleft lip and/or cleft palate. The ectodermal abnormalities affect structures derived from the ectoderm, including the skin, hair, nails, teeth, and sweat glands. Skin findings are particularly prominent and can include severe, chronic skin erosions that may be present at birth and resemble a scalded appearance, especially on the scalp. Hair is typically sparse, wiry, and coarse, and nails may be dystrophic or absent. Dental anomalies include small, widely spaced, or missing teeth. Reduced sweating (hypohidrosis) due to sweat gland involvement can lead to heat intolerance. The skin erosions in AEC syndrome can be extensive and debilitating, sometimes persisting for years and posing a risk of secondary infection. Additional features may include lacrimal duct abnormalities, hearing loss, limb anomalies such as syndactyly, and occasionally genitourinary malformations. Growth and intellectual development are typically normal, though chronic skin disease can significantly impact quality of life. Treatment of AEC syndrome is symptomatic and multidisciplinary. Cleft lip and palate are managed surgically. Skin erosions require careful wound care, infection prevention, and sometimes specialized dressings. Dental abnormalities may require prosthetic intervention. Patients benefit from coordinated care involving dermatologists, plastic surgeons, ophthalmologists, otolaryngologists, and dentists. Genetic counseling is recommended for affected families. There is currently no cure or targeted therapy for the underlying genetic defect.
