If Rett syndrome is a chromosomal abnormality what is the abnormality?
Rett syndrome is not primarily caused by a chromosomal abnormality, but rather a genetic mutation in the MECP2 gene located on the X chromosome. This gene provides instructions for making a protein that is important for brain development. Mutations in the MECP2 gene disrupt the production of this protein, leading to the characteristic features of Rett syndrome.
What are facts about Rett Syndrome?
Rett syndrome is a rare genetic disorder that primarily affects girls. It leads to severe impairments in cognitive, motor, and communication skills. Symptoms typically appear between 6-18 months of age and can include loss of purposeful hand skills, seizures, and breathing abnormalities. Treatment focuses on symptom management and supportive therapies.
How rare is Rett Syndrome?
According to the International Rett Syndrome Foundation, it occurs in 1 out of every 10,000 to 23,000 female births. It is very rare, so the rate of occurrence is not known absolutely. Almost all of those alive with Rett Syndrome are female; males who have the genetic mutation do not have a second X chromosome to compensate for the defective gene so they usually die before birth or shortly thereafter. The males that survive almost always have an extra X chromosome (XXY).
Is Rett syndrome dominant or recessive?
Rett syndrome is a rare genetic disorder that is typically caused by a mutation in the MECP2 gene located on the X chromosome. It is not classified as dominant or recessive in the traditional sense because it primarily affects individuals with two X chromosomes. It is considered an X-linked dominant disorder with variable expressivity and reduced penetrance.
What is a chromosomal disorder that could result from nondisjunction?
Disorders, such as Down's Syndrome, are caused by nondisjunction.
What is the male version of Rett syndrome called?
Rett syndrome in boys is known as Rett syndrome. Male fetuses with Rett syndrome do not typically survive until birth unless they have an extra X chromosome (XXY).

Rett syndrome is rarely seen in boys.The chances of a family having a second child with Rett syndrome are less than one percent.Why Does Rett Syndrome Mostly Affect Girls and Not Boys?Girls have two X chromosomes in every cell. If they have Rett syndrome, some of the cells will use the defective gene. Other cells will use the healthy genes which will help to make up for the cells using the defective gene. However, boys only have one X chromosome in every cell. They lack the extra X chromosome that can protect their bodies from being completely overcome by the disorder. Therefore boys with the cell mutation that causes Rett syndrome often die before or shortly after birth
