Retinitis pigmentosa and hypogammaglobulinemia.

This report describes a family demonstrating an unusual association of retinitis pigmentosa and hypogammaglobulinemia. The proband in this family suffered from another rare illness, ie, Sertoli cell only syndrome. The incidence of retinitis pigmentosa is 1 in 5,000 and that of common variable immunodeficiency state is 1 in 100,000, making a chance association of these illnesses very unlikely.
