What kind of mutation is Rett syndrome?
Mutations in a gene called MECP2 underlie almost all cases of classic Rett syndrome and some variant forms of the condition. This gene provides instructions for making a protein (MeCP2) that is critical for normal brain function.
What gene is responsible for Rett syndrome?
Many researchers now consider Rett syndrome as part of a spectrum of disease relating to mutations of the MECP2 gene. This spectrum, sometimes referred to as MECP2-related disorders, includes classic Rett syndrome, variant Rett syndrome, MECP2-related severe neonatal encephalopathy, and PPM-X syndrome.
Is Rett syndrome a single gene disorder?
Most cases of Rett syndrome are caused by a change (also called a mutation) in a single gene. In 1999, NICHD-supported scientists discovered that most classic Rett syndrome cases are caused by a mutation within the Methylcytosine-binding protein 2 (MECP2) gene. The MECP2 gene is located on the X chromosome.

Why do they call it Angelman Syndrome?
Angelman syndrome was once known as ‘happy puppet syndrome’ because of the child’s sunny outlook and jerky movements. It is now called Angelman syndrome after Harry Angelman, the doctor who first investigated the symptoms in 1965. Most diagnoses are made between the ages of two and five years of age.
Is Angelman Syndrome a disability?
Due to its recognition as a rare genetic and severely disabling disease, Angelman Syndrome is listed by the SSA as a Compassionate Allowance.
Can people with Angelman syndrome have kids in the future?
If your child with Angelman inherited the disease from you and your partner, you may be able to minimize the risk of future children inheriting it. Reproductive technologies such as in vitro fertilization, known as IVF, and pre-implantation genetic diagnosis may provide some options.
Is Angelman syndrome detectable prior to birth?
However, for diseases like Angelman syndrome, a genetic test may be necessary to diagnose your baby before birth. There are two methods to obtain DNA from the fetus while it is still in the womb: amniocentesis or chorionic villus sampling (CVS).
