Autism spectrum disorders (ASD) are developmental disorders with particular social, communication and behavioural problems. Genetic alterations are risk factors for the development of ASD in addition to other mostly unknown causes. ASDs appear in early childhood, four times more frequently in boys than girls. Inheritance is generally multifactorial, i.e. several genes interact in a complex way with each other and with environmental influences. Inconspicuous genetic findings tend to be the rule.
