Abstract
|
|
|
|
Ankyloblepharon-ectodermal defects-cleft lip and/or palate (AEC) syndrome, also known as Hay-Wells syndrome, is a rare autosomal dominant disorder characterized by congenital ectodermal dysplasia. It is caused by mutations in p63 gene. Six isoforms are generated from the TP63 gene mutation and the main isoform expressed in postnatal skin is Np63a, which functions as a key regulator of epidermal integrity. We have experienced a 1-day-old female baby with skin erosions, ankyloblepharosis, and cleft palate that require treatment for skin care and feeding difficulties. Missense mutation in TP63 1657th T → A transition was found in the genetic test performed in the patient, and this genotype has not been reported in a previously variant. The patient was found dead at 91days of birth and the cause of death was estimated by aspiration.
