Rubinstein-Taybi syndrome is a rare disorder characterized by craniofacial dysmorphisms, thumb and hallux alterations, associated with growth and mental deficiency. We describe a 25-year-old male patient, classically presenting the phenotypic features of the syndrome, who sought allergologic evaluation to assess the possibility of food allergy due to the presence of eosinophilic esophagitis. Evaluation with specific tests were normal. Further investigation showed a history of severe systemic infections that had not yet been properly screened, and laboratory investigation showed a deficiency in the production of Immunoglobulin G and its subclasses, as well as specific antibodies. He had no cytopenias, and lymphocyte immunophenotyping was normal. We aim to show that considering the recurrence of infections, notably severe ones requiring hospitalization, an adequate immunological evaluation should be performed in these patients.
