This paper describes the application of enzyme replacement therapy for X-linked hypohidrotic ectodermal dysplasia in dogs. Ectodysplasin A fused to the Fc portion of human immunoglobulin G1 was administered to the dogs in th neonatal period. This treatment improved the teeth  weight gain, restored lacrimation, preventing eye infections and keratoconjuctivitis sicca, induced the formation of moderate numbers of functional sweat glands, and significantly improved mucociliary clearance in the respiratory tract that correlated with the marked decrease of pulmonary diseases in the treated dogs.
