For All Families

Whether your loved one was diagnosed yesterday or 20 years ago or more, we share a common bond. Several members of our staff and most of our trustees have a teenage or older child with Rett syndrome. Like you, there is nothing we want more than to heal our children. We have so many reasons to be confident that your child and ours will benefit from the research that RSRT is advancing.

We recognize that you may have as much or more experience than we do with living with Rett syndrome. You also likely know the Rett community well. We want to know you and to learn from you.


Daybue™ (trofinetide)

In March 2023 the FDA approved DAYBUE as a treatment for Rett syndrome. Our science team, in response to many families asking for our help in understanding the results of the clinical trial, prepared a document called DAYBUE (Trofinetide): Key Facts for Parents (click below). The purpose of this document is to provide facts to help families and their physicians make their own risk: benefit assessment about DAYBUE.

About Rett Syndrome

Imagine the symptoms of autism, cerebral palsy, Parkinson’s disease, epilepsy, and anxiety disorder … all in one little child.

Rett syndrome is a serious, lifelong neurological disorder that is caused by random mutations in a gene called MECP2. Diagnosed primarily in girls, symptoms typically appear in toddlerhood. Many children with Rett are unable to speak, walk, or use their hands. Breathing problems, feeding tubes, seizures, anxiety, and gastrointestinal and orthopedic issues are common. Despite the debilitating nature of the disorder our children are so much more than a laundry list of symptoms. Their beauty and their strength inspire and motivate us.

Rett syndrome stands apart from other neurological disorders due to the dramatic reversibility of symptoms in animal models.

Our confidence that Rett syndrome is curable guides our every decision.

Although rare, boys can also have Rett syndrome. Please visit our Genetics Primer to learn more. With the exception of the MECP2 Reactivation strategy all the research that RSRT supports is also applicable to boys.

Genetics 101

Mutations in a gene called MECP2 were identified as the cause of Rett syndrome in 1999, in the laboratory of Huda Zoghbi, MD, at Baylor College of Medicine. First discovered by Adrian Bird, PhD, in 1992, MECP2 produces a protein, also called MECP2, which regulates the activity of other genes. In most cases, the damaged copy of MECP2 can be traced to a random mutation in sperm. The incidence of recurrence in a family is less than 1%.

Although Rett syndrome remains a clinical diagnosis based on the child’s symptoms and history, the identification of MECP2 has made DNA testing and confirmation possible for affected individuals and their families. To date, approximately 95% of girls with a clinical diagnosis of Rett have a confirmed MECP2 mutation.
