ankyloblepharon-ectodermal defects-cleft lip/palate

An autosomal dominant condition (OMIM:106260) characterised by congenital ectodermal dysplasia with sparse coarse and wiry hair, dystrophic nails, slight hypohidrosis, scalp and skin erosion, ankyloblepharon filiform adnatum, maxillary hypoplasia, hypodontia, and cleft lip/palate.

Molecular pathology
Caused by defects of TP63, which encodes a p53 transcription factor that acts as a sequence-specific DNA-binding transcriptional regulator of epithelial morphogenesis and required for limb formation from the apical ectodermal ridge.
