Autism may contain sub -types that are genetically separated from each other

It seems that the age at which children are diagnosed with autism are partially affected by their genetics, which may also affect how the condition develops.

“This really supports the idea that autism is actually a number of situations,” says Natalie Swallid at the New York’s Flatieron Institute.

Autism is a neurode -developmental state, which is characterized by limited behavior and interests in addition to difficulties with social interaction. The World Health Organization estimates that one in the 127 is autistic.

“The key question we were interested in was: Why are there some autistic people whose life is diagnosed later?” Varun Warner says at Cambridge University.

To find out, he and his colleagues made statistics about those who were diagnosed with autism between the ages of 5 and 17. Their careers completed a question mark about their social, emotional and behavioral growth, to help the team see if these factors are associated with their age at the time of diagnosis.

Along with the sex of a child, their socio -economic status, has been associated with age at the time of diagnosis – the initial diagnosis is more common in boys and rich backgrounds – but team analysis shows that these effects are actually weak. “Generally, no factors explain more than 10 percent change,” says Warir.

Instead, the team found evidence of developing autistic children at different pace. “What we got was that the autistic people were groups in two wide groups,” says Warir. A group began to face difficulties in early life and remained widely permanent. The other had less difficulties in early childhood, but had more experienced in childhood and early youth. He says he has explained “anywhere between 10 and 25 percent of the diagnosis of autism.”

Moreover, researchers found that these differences between the two groups were reflected in the children’s DNA, which were previously collected. Later diagnosis contains a different set of common genetic variations than previously diagnosed, which describes 11 % variations at the age of autism. The team did not have the rare variations or their searching nessary data that arise instead of inheriting.

Sweet Wald says that despite these two tricks, there is no sign of severe separation between them. She says, “There is an overlap between your groups, probably because they are not separate.” The Warrir likewise describes them as the current “gradual”.

He emphasized that no group should be thought of whether it is mild or more severe autism, which rapidly suggests research that many shapes take. In July, Sovere Wald and his colleagues published a study in which they found evidence of four moderate separate groups, including various symptoms, behaviors and basic genetics.

The Warrior team also found that later diagnosed children are more likely to have genetic variations, including other conditions, including ADHD and post -traumatic stress disorder. In a Swor -Walled study, his team found a similar link between the diagnosis of late autism and ADHD, which is a form of neurodecycle, like autism. Savar Wald says why this link is available. “There is a wonderful lack of data on ADHD,” he says, especially about people’s specific symptoms.

Better understanding the potential sub -types of autism can ultimately help improve diagnostic methods, and can lead to more appropriate support for autistic children and their families. “This can only improve the standard of living of individuals – when we can better understand their condition, and how to help them, and what is it that they need and what they do not need,” says Warir.
