AUTISM
BY MANNY(:
2.
FACTS
Children with autism carry twice as many new and damaging genetic mutations as typically developing children.
The syndrome is caused by the loss of FMRP.
FMRP is a protein that controls the translation of genes into proteins at the synapse, or junction between neurons.
About two dozen genes on that long list are hit by spontaneous mutations in some children with autism.
3.
STUDIES
The study also showed that the parents are much less likely to carry killer mutations in the FMRP.
FMRP is involved in a huge family of genes with many complex roles in the brain.
Wigler estimates that about 350 genes will be linked to autism.
Previously-held perception says older mothers are more likely to have children with autism.

HOW AUTISM IS DIAGNOSED
no babbling or pointing by age 1.
no single words by 16 months or two-word phrases by age 2.
no response to name .
no smiling or social responsiveness.

CAUSES OF AUTISM
Scientists aren’t certain about what causes ASD.
it’s likely that both genetics and environment play a role.
Studies of people with ASD have found irregularities in several regions of the brain.
Other studies suggest that people with ASD have abnormal levels of serotonin or other neurotransmitters in the brain.

INHERITANCE ROLE
Twin and family studies strongly suggest that some people have a genetic predisposition to autism.
In families with one child with ASD, the risk of having a second child with the disorder is approximately 5 percent
Evidence also suggests that some emotional disorders, such as bipolar disorder, occur more frequently than average in the families of people with ASD.
Researchers are looking for clues about which genes contribute to this increased susceptibility.

HOW IS IT TREATED?
There is no cure for ASDs.
Therapies and behavioral interventions are designed to remedy specific symptoms and can bring about substantial improvement.
Medications: Doctors may prescribe medications for treatment of specific autism-related symptoms, such as anxiety, depression,
Other therapies: There are a number of controversial therapies or interventions available, but few, if any, are supported by scientific studies.
