RT Journal Article SR Electronic T1 Agammaglobulinemia and Thymic Dysplasia Associated with Ectodermal Dysplasia JF Pediatrics JO Pediatrics FD American Academy of Pediatrics SP 143 OP 147 VO 47 IS 1 A1 Feigin, Ralph D.

YR 1971 UL http://pediatrics.aappublications.org/content/47/1/143.abstract AB A 5-month-old female with agammaglobulinemia, thymic dysplasia, ectodermal dysplasia, and an erythematous icthyosiform dermatitis has been presented. Death at 7 months of age was the result of pneumocystis carinii pneumonia. The association of a broadly based immunologic deficit with ectodermal defects noted at birth lends support to the concept that a basic genetic abnormality may disturb the development of a number of mesenchymal components. It also suggests that skeletal anomalies are not invariably associated with the immunologic and ectodermal defects.
