Uniting families, scientists, and clinicians—we advance patient-centered research and support for everyone impacted by Tatton Brown Rahman Syndrome (TBRS).
Tatton Brown Rahman Syndrome (TBRS) is a complex and rare disorder characterized by overgrowth, varying degrees of intellectual disability, and characteristic facial features that become more apparent with age. TBRS can affect many systems in the body.
Individuals may present with autism, joint hypermobility, low muscle tone, kyphoscoliosis, seizures, behavioral and mental health disorders, heart defects, obesity, hearing and vision concerns, sleep apnea, blood disorders, and an increased risk for certain cancers, especially leukemia.
