-
A basal subtype of epidermolysis bullosa simplex characterised by generalised blistering associated with muscular dystrophy. Onset of blistering is usually as early as birth, muscular dystrophy manifests between infancy and adulthood. Blisters are often haemorrhagic and heal with mild atrophic scarring and rare milia formation. Associated findings comprise markedly dystrophic nails, and focal keratoderma of the palms and soles. Extracutaneous involvement is usually present. Caused by mutations in the PLEC gene (8q24) encoding plectin. Plectin deficiency can be demonstrated in skin and muscle by analysis with specific antibodies. Transmission is autosomal recessive.
