This is much evidence that there is a genetic susceptibility to autism.{{fact}} The genetics of this condition are not yet fully understood and could be caused by complex interactions between multiple genes which would account for the "spectrum" like differences in the severity of many cases <ref> http://66.102.1.104/scholar?hl=en&lr=&q=cache:7kMNqvTgRtoJ:www.ikhebeenvraag.be/mediastorage/FSDocument/52/Freitag-2.pdf+</ref><ref>http://www.ncbi.nlm.nih.gov/pubmed/17764594</ref>
