Autism Is Largely Down to Genes, Twins Study Suggest

(BBC) – Genetic influences on autism are estimated to be between 74-98%, a Medical Research Council study of 258 twins suggests. The King’s College London team said 181 of the teenagers had autism, but the risk was far higher in identical twins where one twin had autism, as they share the same DNA. The researchers told JAMA Psychiatry that hundreds of genes were involved. But they do not rule out environmental factors.
