    Coping With Rett Syndrome
    A debilitating disorder that strikes only girls, Rett Syndrome challenges physicians, patients, and families. One symptom of Rett Syndrome is profound growth failure. Pediatrician and nutritionist Kathleen J. Motil with the USDA- ARS Children's Nutrition Research Center (CNRC) in Houston, Texas, is finding innovative ways to promote adequate nutrition, improve health, and enhance growth for some of these patients. Rett Syndrome occurs in 1 out of 23,000 live births. The onset is baffling: A healthy, active infant gradually stops developing normally. Typically, she regresses, losing her speech and walking skills, as well as the ability to play with toys. Repetitive hand-wringing and hand-washing movements are common, as are breathing abnormalities. Growth failure and muscle wasting may occur as early as 1 year of age. Motil and others have done studies suggesting this poor growth and wasting may be linked in part to the girls' need for special nutritional care. Andreas Rett, the medical doctor who first described this neurodevelopmental disease in 1966, noted the symptoms of wasting and slowed growth. Growth retardation is one of the factors supporting the diagnosis of Rett Syndrome. Other researchers, including Motil's colleagues, pediatric neurologist Daniel G. Glaze and nurse practitioner Rebecca J. Schultz, have reported in medical journals a deceleration in the rate of gain in head circumference, height, and weight.

    collection of gene-related information OMIM catalog of human genes and disorders Information Information Sheet from the National Institute of Neurological Disorders and Stroke, NIH International Rett Syndrome Association support and information for families RETT SYNDROME (RTT) is a progressive neurodevelopmental disorder that almost exclusively affects females. It has an incidence of about 1 in 10,000 births, making it one of the most common causes of profound mental retardation in girls. Individuals with RTT develop normally until the age of 6 to 18 months, when they begin to lose purposeful use of their hands and speech. Affected individuals also show reduced muscle tone, wringing hand movements, autistic-like behavior and seizures. A gene which causes RTT, , has been found on the long arm of chromosome X (Xq28). Normally, females have two X chromosomes and males have an X and a Y. Since males do not have an additional copy of X to offset a defect, most X-linked diseases affect males. Then, why are males not affected by RTT? One possible explanation is that the absence of a functional copy of

    flirting My PhotoGallery - From 3 Months to 12 Years About Rett Syndrome
    Rett Syndrome (RS) is a neurodevelopmental disorder believed to affect 1 in 10,000 female births (rarely seen in males). It is named for Dr. Andreas Rett, an Austrian physician who identified the syndrome in 1966, although it remained unknown in the United States until 1983.
    Symptoms: Children with Rett Syndrome appear to develop normally until 6 to 18 months of age. They then enter a period of regression, losing speech and hand skills they had acquired. Most children develop seizures, repetitive hand movements, irregular breathing and motor-control problems.* A slowing of the rate of head growth also becomes apparent. Most researchers agree that RS is a developmental disorder rather than a progressive, degenerative disorder. The girls can live to adulthood, but most never regain the ability to use their hands or to speak.
    Cause: In 1999, a research team led by Dr. Huda Y. Zoghbi of the Howard Hughes Medical Institute and Houston’s Baylor College of Medicine identified the cause of Rett Syndrome as a defect in the MECP2 gene on the X chromosome. RS is most often misdiagnosed as autism, cerebral palsy or non-specific developmental delay. Genetic testing is now available to confirm the diagnosis.

    printer friendly RETT SYNDROME home more about us in your area conditions information ... how you can help search this site Rett syndrome is the clinical expression of the Rett disorder, a complex, genetic, neurological condition which affects far more girls than boys. Although signs may not be initially obvious, it is present at birth. It usually becomes more evident during the second year. People with Rett syndrome are almost always profoundly and multiply disabled and totally dependent on others for all their needs throughout their lives but severity may vary considerably. The baby with classic (easily recognised) Rett syndrome is usually placid and rather inactive. Learning may be slow but progress may reach the 9 or 12 month stage, occasionally beyond. Within a few weeks of birth the child's head size may fail to increase at the normal rate indicating failure of the brain to grow normally, although head size may remain within normal limits. Strange finger movements develop with the hands twisting and squeezing rather than reaching out to explore. Usually between one and three years the abnormal hand movements become more obvious and purposeful use is reduced or lost. During this time of regression the child may be agitated and distressed and breathing rhythm becomes irregular. Brain scans may confirm poor growth of the brain and after some months the electroencephalogram may show abnormal electrical activity in the brain cells (an electroencephalogram is the tracing which shows the electrical activity due to the neurones on the surface of the brain). There is disturbance of several substances involved in brain development and mature function. The diagnosis is confirmed by detecting a mutation (fault) on MECP2, a gene at the tip of the X chromosome. In just a few people with all or most of the clinical signs of Rett a mutation has not been found and it is possible that these people have a fault affecting control of MECP2 or of genes whose activity should be regulated by MECP2.

    Rett Syndrome Traced to Defective Gene "Silencer"
    "Finding that gene is the hardest thing I've ever worked on," says HHMI investigator Huda Zoghbi. A 14-year search for the cause of a rare genetic disease that strikes young girls has uncovered the first example of a human disease that is linked to a defective gene silencing mechanism. Rett syndrome (RTT) is a neurodevelopmental disorder seen in young girls that causes a sudden and permanent decline in mental capabilities. In 1985, HHMI investigator Huda Zoghbi , who was then a neurology fellow, published a clinical research report on Rett syndrome. Her initial encounter with the disorder had a lasting impact on her career. Shortly after seeing her first RTT patients, Zoghbi decided to change her career plans, switching from clinical medicine to a research position. Shortly after switching to research, she started the long, tedious search for the genetic causes of RTT. "Finding that gene is the hardest thing I've ever worked on," Zoghbi said in an interview. "It's the best case for the rewards of perseverance that I can think of."

By studying gene mutations in patients with the complex set of behavioral and neurological symptoms that accompany Rett syndrome, Howard Hughes Medical Institute investigator Huda Zoghbi and her colleagues at Baylor College of Medicine have designed a mouse model that faithfully recapitulates the disease down to its distinctive hand-wringing behavior.

    Home DRAGON SNOMAD Bioinformatics ... Publications Introduction Autism and Rett Syndrome are devastating, lifelong neurological disorders that are classified as pervasive developmental
    disorders (sometimes abbreviated PDD). Autism and Rett Syndrome are characterized clinically by severe, pervasive
    impairment in communication skills and in reciprocal social interaction skills. Stereotyped behavior and interests are
    typical. In many cases, autism and Rett Syndrome are accompanied by mental retardation as well as seizures. These
    disorders cause significant hardships for the affected children and adults, as well as their families, schools and
    communities. Today, the diagnosis of autism and related pervasive developmental disorders such as Asperger's Syndrome is based
    upon clinical criteria. There are no known biological causes. There are very few proven neurochemical, genetic,
    neuroanatomical, neurophysiological, structural, metabolic, or other molecular differences between these patients and the
    normal population.

    Mouse With Rett Syndrome May Provide Model for Testing Treatments, Understanding Disorder Neuron The researchers regard the mouse as an improvement over other animal models of the disease because the mice exhibit physical and behavioral characteristics that mimic Rett syndrome in humans much more closely than did earlier mouse models for the disorder. “The generation of a strain of mice that have the features of Rett syndrome is an important advance in the quest to understand and prevent this devastating disorder,” said Duane Alexander, M.D., Director of the NICHD. “By studying these mice, researchers will be able to learn more about the natural progression of Rett syndrome, as well as test medications and other treatments that might prevent or lessen the symptoms of the disorder.” The strain of mice developed by the researchers appeared normal for about six weeks, but then developed a progressive disease that closely mimics Rett syndrome in humans. For example, the mice developed tremors, problems with muscle control, seizures and curvature of the spine. They also appeared anxious and moved their front limbs in a motion similar to the constant hand-wringing seen in girls with Rett syndrome. Over time, the mutant mice appeared unkempt, most likely as a result of a lack of normal grooming. Their social interaction was impaired and normal mice actively avoided them.
