title: Callosal agenesis, iris coloboma, and megacolon in a Brazilian boy with Rubinstein-Taybi syndrome.
abstract: We report on a Brazilian boy with Rubinstein-Taybi syndrome (RTS) with callosal agenesis, iris coloboma, and megacolon. To our knowledge, callosal agenesis, iris coloboma, and megacolon are unusual signs within the clinical spectrum of RTS, and the present association is apparently underscribed.
