We are grateful to Liam Devlin & Co., Dublin, Ireland, and Geo Bassett & Co., Owterton, Sheffield, England, for much heIp and also for the supply of confections; Messrs. Devlin supplied the crude licorice extract. Dr. C. Nieman of the Centraal Insthuut voor de Dropverwerkende Industrie in Amsterdam kindly carried out glycyrrhizic acid assays and gave much helpful advice. REFERENCES

swelling of the knees. Studies of the synovial fluid obtained by needle puncture of ,he knee showed no inflammatory, cells a n d a bacterial culture was negative. Serum immunoglobulin concentrations for the p r o b a n d and her parents are shown in Table I. I g A was not detected in the serum and' saliva of the patient. T h e I g A concentrations for the parents were normal. T h e mother and patient had a somewhat elevated I g M . Rectal mucosa of the patient was obtained by suction biopsy for immunocytochemical studies; there were plasma cells in the lamina propria, but the normal ratio of I g A to I g M positive plasma cells was reversed. T h e ,patient had blood group A, negative direct and indirect Coombs' test, positive anti-B isohemagglutinins at a titer of 1:128, and a negative Schick test. She received the usual childhood immunization for diphtheria. Routine peripheral blood cell counts, lupus erythematosus preparations, sedimentation rates, serum mucoproteins, antistreptolysin titer, rheumatoid factor, and antinuclear factor were all normal. T h e patient studied by Smith and D a e n t P had a deletion of the short arm of chromosome No. 18~ deficient !gA, and presented with " r h e u m a t o i d arthritis." W e could not establish such a diagnosis for the recurrent swelling of t h e knees observed in our patient. Ever/ though 0.14 to 0.42 per cent of clinically healthy individuals possess no detectabIe !gA, 6 and t h e serum and saliva IgA have been found normal in at least one patient with a ring No. 18 chromosome, ~ the immunoglobulin abnormalities, as well as

other isolated metabolic defects 7 observed in association with defects of chromosome No. 18, may be more than coincidental. T h e possibility that a gene locus for I g A c a n be shown on one a r m of pair No. 18 has become less simple in view of reports now available. 7 T h e genetic aspects of these cases will be discussed elsewhere. At this time we wish to emphasize the need for immunoglobulin studies of all patients with chromosomal deletions, and for chromosome studies of individuals with multiple congenital anomalies associated with immunologic disorders. The chromosome analyses of the parents were performed at the Joint Cytogenetics Service Laboratory, Rainier School. The serum immunoglobulin and blood analyses were performed at the Immunology Laboratories of the Department of Pediatrics, University of Washington, and in the clinical laboratory of Rainier School. The examination of the rectaI mucosa biopsy was performed by Dr. Shmuel Eidelman, Department of Medicine, University of Washington. The Laboratories of the King County Central Blood Bank, Seattle, performed the isohemagglutin titer. REFERENCES 1. Finley, S. C., Finley, W. H., Noto, T. A., Uchida, I.
