Environmental Risk Factors
ASC affects 1 in 59 children worldwide, with 4 boys to every girl diagnosed. This rising prevalence represents a 35-fold increase since the earliest epidemiologic studies were conducted in the late 1960s. Although genetics influence the risk of developing ASC, genetics alone cannot explain the increased incidence. What is more likely is that ASC is a combination of genetic and environmental risk factors. The study of environmental risk factors is in its infancy and is a crucial area of study. ICAN is investigating the identification of pre-natal, and post-natal risk factors associated with future onset of ASC.
