Autism or something else
Children with a genetic disorder known as 22q11.2 deletion syndrome (22q) who are also frequently thought to have autism spectrum disorder (ASD) are often misdiagnosed, new research suggests.
Social impairment associated with the developmental delays from 22q may be mimicking the features of ASD, which can then lead to an ASD misdiagnosis, according to investigators.
Results from the study showed that of 29 children with 22q, none met the strict diagnostic criteria for autism ― which include elevated scores on both the gold standard Autism Diagnostic Observation Schedule (ADOS) and the Social Communication Questionnaire (SCQ).
