CHILD DEVELOPMENT PEDAGOGY

Detailed explanation-1: -Genetic factors are estimated to contribute 40 to 80 percent of ASD risk. The risk from gene variants combined with environmental risk factors, such as parental age, birth complications, and others that have not been identified, determine an individual’s risk of developing this complex condition.

Detailed explanation-2: -What causes autism spectrum disorder? Although the cause of ASD is known in some people and not known in others, genetics, biology, and environment are all important factors. Having older parents, a difficult birth, or infections during pregnancy are all examples of factors that might increase the risk for having ASD.

Detailed explanation-3: -Autism spectrum disorder has no single known cause. Given the complexity of the disorder, and the fact that symptoms and severity vary, there are probably many causes. Both genetics and environment may play a role.

Detailed explanation-4: -The team found that mothers passed only half of their structural variants on to their autistic children-a frequency that would be expected by chance alone-suggesting that variants inherited from mothers were not associated with autism. But surprisingly, fathers did pass on substantially more than 50% of their variants.
