Bilateral sensorineural deafness in adenosine deaminase-deficient severe combined immunodeficiency.

With improved survival, the nonimmunologic manifestations of this condition are becoming apparent. We report a high incidence of bilateral sensorineural deafness in transplanted patients, which highlights the systemic nature of the disease.
