A novel mutation for TAP deficiency and its possible association with Toxoplasmosis.

We describe two siblings (a male patient and his older sister) with a novel mutation in the peptide transporter associated to antigen processing (TAP). The index case presented with not only granulomatous skin lesions and recurrent sino-pulmonary infections, often associated with this deficiency, but also a severe pulmonary toxoplasmosis. His toxoplasmosis and skin lesions were successfully treated.
