Scientists have been studying genes to learn more about autism. Most people have an idea of what autism is- the condition is not rare amongst children and affects their ability to integrate and develop relationships with other people.
These individuals often have problems interacting with the world around them making schooling, education, socializing and family life hard.
To be more precise, Autism is actually Autism Spectrum Disorder- this is because there is such a huge range of types of autism that is hard to classify them under just one heading because they are not all the same; people with autism can vary immensely from one to the other.
Types of Autism
- Childhood disintegrative disorder
- Rett Syndrome
- Pervasive development disorder
In terms of genes and the genes that might cause autism, new, revealing research has emerged. There are links between the genes responsible for autism and other illnesses. Genetic mutations take place in kids with the disorder that cause it to happen. Children without these mutations do not develop autism. The genes that are linked to autism are often located next to other genes which are themselves responsible for other brain disorders. These disorders include:
- Hyperactivity and ADD (attention deficit disorder)
- Obsessive Compulsive disorders (OCD)
- Bipolar Disorders
Genetic testing and the studies on the genes causing autism continue. Scientists need to find out why, for example, boys are more likely to be affected than girls. How many actual mutations are there and whether each form of autism is linked to its own peculiar gene?
Twin studies have shown that identical twins are much more likely to share autistic traits. This proves there is a genetic component. Genes are responsible for autism.
