Health Conditions

Pitt-Hopkins Syndrome

Pitt-Hopkins Syndrome is a rare genetic disorder that causes developmental, intellectual, and physical disabilities. Only about 500 people globally are known to have Pitt Hopkins Syndrome.

Symptoms

Patients with Pitt-Hopkins Syndrome can experience:

  • Delays in learning how to walk

  • Difficulty with communication

  • Constipation

  • Epilepsy

  • Microcephaly, abnormally small head size

  • Nearsightedness

  • Crossed eyes

  • Trouble breathing

Causes

Pitt-Hopkins syndrome is caused by a mutation in the TCF4 gene. This gene is in charge of proteins that affect the development of the brain and nervous system. A child is at a 50% higher risk of developing the condition if one parent also has the mutation, however, in the majority of cases the mutation is not inherited.

Treatment

Pitt-Hopkins syndrome is not curable, but there are treatment options to help manage symptoms. These may include physical, occupational and speech therapies, epilepsy management medications, psychiatric and behavioral medications and/or stool softeners and laxatives for gastrointestinal symptoms.

Microbiota Therapy Research

Achieving Cures Together research partners at Arizona State University are investigating the effect of microbiota transplant therapy on patients with Pitt-Hopkins disease.

  • Microbiota Transfer Therapy for Children and Adults With Both Pitt Hopkins Syndrome and Gastrointestinal Disorders
    Trial Location: Arizona State University – Tempe, AZ
    Trial Status: Underway
    Trial Summary:
    Researchers at Arizona State University are studying the safety and efficacy of Microbiota Transplant Therapy in treating patients with Pitt-Hopkins Syndrome and gastrointestinal symptoms through a Phase II clinical trial.

  • <strong>MTT for Children With Both Pitt-Hopkins Syndrome and Gastrointestinal Disorders</strong>
    <strong>Trial Location:</strong> Arizona State University – Tempe, AZ
    <strong>Trial Status:</strong> Completed
    <strong>Trial Summary:</strong>
    Dr. Adams and Dr. Krajmalnik-Brown at Arizona State University led a Phase 2, double-blind, placebo-controlled trial assessing the impact of Microbiota Transfer Therapy in patients with Pitt-Hopkins Disease, a genetic disease associated with a severe form of Autism. The study demonstrated microbiota transfer therapy is safe in Pitt-Hopkins patients. Additionally, improvements in gastrointestinal and other Pitt-Hopkins symptoms were seen.
