Study Links Autism Severity to Genetics, Ultrasound
September 2, 2016
(Eurekalert) – For children with autism and a class of genetic disorders, exposure to diagnostic ultrasound in the first trimester of pregnancy is linked to increased autism severity, according to a study by researchers at UW Medicine, UW Bothell and Seattle Children’s Research Institute. The study published Sept. 1 in Autism Research studied the variability of symptoms among kids with autism, not what causes autism. What they found is that exposure to diagnostic ultrasound in the first trimester is linked to increased autism symptom severity. The greatest link is among kids with certain genetic variations associated with autism; 7 percent of the children in the study had those variations.
