Rubinstein-Taybi syndrome: an immune deficiency as a cause for recurrent infections

Allergy Asthma Proc. 2006 May-Jun;27(3):281-4. doi: 10.2500/aap.2006.27.2864.


Rubinstein-Tabyi Syndrome (RTS) is characterized by broad toes, broad thumbs, facial dysmorphisms, and mental retardation. The syndrome has been shown in some patients to be associated with break points in and microdeletions of chromosome 16p13.3. It is estimated that approximately 75% of patients with RTS experience recurrent respiratory infections. In this study, three patients thought to have RTS and recurrent infections were evaluated for an immunologic deficiency. All three patients showed a polysaccharide antibody response deficit. We conclude that a primary immune deficiency may exist in the remainder of the RTS population and may explain the reason for the propensity for recurrent infections. Aggressive investigation and management in patients with RTS may further determine the mechanism of this deficiency and enhance the quality of life of these patients.
