What is Rett Syndrome?
Rett syndrome is a postnatal neurological disorder seen almost always in girls, but can be rarely seen in boys. It is not a degenerative disorder.

Rett syndrome is caused by mutations on the X chromosome on a gene called MECP2. There are more than 200 different mutations found on the MECP2 gene. Most of these mutations are found in eight different “hot spots.”

Rett syndrome strikes all racial and ethnic groups, and occurs worldwide in 1 of every 10,000 to 23,000 female births.

Rett syndrome causes problems in brain function that are responsible for cognitive, sensory, emotional, motor and autonomic function. These can include learning, speech, sensory sensations, mood, movement, breathing, cardiac function, and even chewing, swallowing, and digestion.

Rett syndrome symptoms appear after an early period of apparently normal or near normal development until six to eighteen months of life, when there is a slowing down or stagnation of skills. A period of regression then follows when she loses communication skills and purposeful use of her hands. Soon, stereotyped hand movements such as handwashing, gait disturbances, and slowing of the normal rate of head growth become apparent. Other problems may include seizures and disorganized breathing patterns while she is awake. In the early years, there may be a period of isolation or withdrawal when she is irritable and cries inconsolably. Over time, motor problems may increase, but in general, irritability lessens and eye contact and communication improve.

Rett syndrome can present with a wide range of disability ranging from mild to severe. The course and severity of Rett syndrome is determined by the location, type and severity of her mutation and X-inactivation. Therefore, two girls of the same age with the same mutation can appear quite different.


Testing and Diagnosis
Rett syndrome is most often misdiagnosed as autism, cerebral palsy, or non-specific developmental delay. In the past, making the correct diagnosis called not only for a long list of diagnostic tests and procedures to rule out other disorders, but it also took from months to years waiting to confirm the diagnosis as new symptoms appeared over time. Today, we have a simple blood test to confirm the diagnosis. However, since we know that the MECP2 mutation is also seen in other disorders, the presence of the MECP2 mutation in itself is not enough for the diagnosis of Rett syndrome. Diagnosis requires either the presence of the mutation (a molecular diagnosis) or fulfillment of the diagnostic criteria (a clinical diagnosis, based on signs and symptoms that you can observe) or both. Below is a list of labs to share with your ordering physician that can do the MECP2 sequencing + deletion analysis, and the list of diagnostic criteria.

Rett Syndrome Awareness Month

Rett syndrome is a rare, severe, “girls only” form of autism. It’s usually discovered in the first two years of life, and a child’s diagnosis with Rett syndrome can feel overwhelming. Although there’s no cure, early identification and treatment may help girls and families who are affected by Rett syndrome.

Who Gets Rett Syndrome?
Rett syndrome is an autism spectrum disorder that affects girls almost exclusively. It’s rare — only about one in 10,000 to 15,000 girls will develop the condition.

In most cases of Rett syndrome, a child develops normally in early life. Between 6 and 18 months of age, though, changes in the normal patterns of mental and social development begin.


What Are the Symptoms of Rett Syndrome?
Although it’s not always detected, a slowing of head growth is one of the first events in Rett syndrome. Loss of muscle tone is also an initial symptom. Soon, the child loses any purposeful use of her hands. Instead, she habitually wrings or rubs her hands together.

Around 1 to 4 years of age, social and language skills deteriorate in a girl with Rett syndrome. She stops talking and develops extreme social anxiety and withdrawal or disinterest in other people.

Rett syndrome also causes problems with muscles and coordination. Walking becomes awkward as girls develop a jerky, stiff-legged gait. A girl with Rett syndrome may also have uncoordinated breathing and seizures.


What Causes Rett Syndrome?
Most children with Rett syndrome have a mutation in a particular gene on the X chromosome. Exactly what this gene does, or how its mutation leads to Rett syndrome, isn’t clear. It’s believed that the single gene may influence many other genes involved in development.

Although Rett syndrome seems to be genetic, the faulty gene is almost never inherited from the parents. Rather, it’s a chance mutation that happens in the girl’s own DNA. No Rett syndrome risk factors have been identified, other than being female. There is no known method for preventing Rett syndrome.

When boys develop the Rett syndrome mutation, they die shortly after birth. Because boys have only one X chromosome (instead of the two girls have), the disease is more serious, and quickly fatal.


How Is Rett Syndrome Diagnosed?
A diagnosis of Rett syndrome is based on a girl’s pattern of symptoms and behavior. The diagnosis can be made on these observations alone. Discussions between a doctor and a girl’s parents will help determine important details, such as when symptoms started.
Genetic testing can help confirm the diagnosis in 80% of girls with suspected Rett syndrome. It’s possible that genetic testing can help predict severity.


Treatments for Rett Syndrome
There are treatments available for Rett syndrome that focus on helping a girl live the best life she can with the condition. Physical therapy can help improve mobility; speech therapy may help somewhat with language problems; and occupational therapy helps girls perform daily activities — like bathing and dressing — independently.

Experts believe that therapy can help girls with Rett syndrome and their parents. Although a “normal” life may not be possible, some improvement can be expected with therapy. Participating in activities — including school — and improved social interaction are sometimes possible.

Medicines can treat some of the problems with movement in Rett syndrome. Medication can also help control seizures. Unfortunately, there is no cure for Rett syndrome.


What to Expect With Rett Syndrome
Many girls with Rett syndrome can be expected to live at least into middle age. Researchers are still following women with the disease, which was only widely recognized in the past 20 years.

Symptoms of Rett syndrome don’t usually improve over time. It is a lifelong condition. Often, there is a very slow worsening of symptoms, or symptoms remain stable. Girls and women with Rett syndrome will rarely be able to live independently.

National Disability Employment Awareness Month, 2013
By the President Of The United States Of America
A Proclamation

Our Nation has always drawn its strength from the differences of our people, from a vast range of thought, experience, and ability.  Every day, Americans with disabilities enrich our communities and businesses.  They are leaders, entrepreneurs, and innovators, each with unique talents to contribute and points of view to express.  During National Disability Employment Awareness Month, we nurture our culture of diversity and renew our commitment to building an American workforce that offers inclusion and opportunity for all.

Since the passage of the Americans with Disabilities Act, we have made great progress in removing barriers for hardworking Americans.  Yet today, only 20 percent of Americans with disabilities, including veterans who became disabled while serving our country, participate in our labor force.  We need their talent, dedication, and creativity, which is why my Administration proudly supports increased employment opportunities for people with disabilities.  To that end, I remain dedicated to implementing Executive Order 13548, which called on Federal agencies to increase recruitment, hiring, and retention of people with disabilities.  As a result of our efforts, the Federal Government is hiring people with disabilities at a higher rate than at any point in over three decades.  Most recently, we updated the rules to make sure Federal contractors and subcontractors are doing more to recruit, hire, and promote qualified individuals with disabilities, including disabled veterans.  And thanks to the Affordable Care Act, States are taking advantage of new options to support and expand home and community-based services.

In the years to come, I will remain committed to ensuring the Federal Government leads by example.  This year, as we mark the 40th anniversary of the Rehabilitation Act, I will continue to marshal the full resources of my Administration toward effective and comprehensive implementation.

If we swing wide the doors of opportunity for our family, friends, and neighbors with disabilities, all of us will enjoy the benefits of their professional contributions.  This month, let us uphold the ideals of equal access, equal opportunity, and a level playing field for all Americans.

NOW, THEREFORE, I, BARACK OBAMA, President of the United States of America, by virtue of the authority vested in me by the Constitution and the laws of the United States, do hereby proclaim October 2013 as National Disability Employment Awareness Month.  I urge all Americans to embrace the talents and skills that individuals with disabilities bring to our workplaces and communities and to promote the right to equal employment opportunity for all people.

IN WITNESS WHEREOF, I have hereunto set my hand this thirtieth day of September, in the year of our Lord two thousand thirteen, and of the Independence of the United States of America the two hundred and thirty-eighth.

BARACK OBAMA
