Centers for Disease Control and Prevention. environmental factors reportedly influenced children with and without disabilities across settings. It is written for all those interested in understanding the causes and pathogenesis of these disorders as well as those involved in the care of affected patients. Gene-environment interactions and the role environmental factors might play in leading to developmental disorders are just beginning to be studied. Folic acid. A research strategy to discover the environmental causes of autism and neurodevelopmental disabilities. Management of a disability. Newborn screening (NBS) is a simple procedure to find out if your baby has a congenital metabolic disorder that may lead to mental retardation and even In what way can these factors influence the course of development?

The Basic Concepts of Human Reproduction Heredity- the mechanism for the transmission of human characteristics from one generation to the next. Abnormalities in genes and genetic inheritance can cause intellectual disability in children. It is assumed that in approximately half of intellectual disability cases, there is no known cause, but more requests are being made to screen for genetic defects in cases of moderate to severe intellectual disability.
