Epidermolysis Bullosa, Lethal Acantholytic

A suprabasal subtype of epidermolysis bullosa simplex characterized by generalized oozing erosions, usually in the absence of blisters. Onset of the disease is at birth. Extracutaneous involvement is always present, involving erosions of the soft tissues of the oral cavity and gastrointestinal, genitourinary and respiratory tract abnormalities. The disease is due to mutations in the DSP (6p24) gene encoding desmoplakin. Transmission is autosomal recessive.
