Study: Clinical criteria for autism diagnosis inadequate for individuals with genetic conditions ANI | Updated: Jan 02, 2021 05:56 IST Washington [US], January 2 (ANI): A new research has discovered that people with certain genetic conditions are likely to have significant symptoms of autism, despite them not qualifying by formal diagnosis. Published in The American Journal of Psychiatry, the international study analysed data from 547 people who had been diagnosed with one of four genetic conditions, also known as copy number variants (CNVs), associated with a high chance of autism - 22q11.2 deletion, 22q11.2 duplication, 16p11.2 deletion and 16p11.2 duplication. Researchers at Cardiff University say their findings show clinical services need to adapt so that people diagnosed with autism-linked genetic conditions are not denied access to vital support and interventions.
