Autism spectrum disorder (ASD) is a group of neurodevelopmental disorders characterized by a combination of reciprocal social deficits, communication impairment, and rigid ritualistic interest and stereotypies. The etiology is generally multifactorial, including genetic, immunological and/or environmental factors. A group of ASD has been linked to mitochondrial dysfunction with subsequent deficiency in energy production. Patients with ASD and mitochondrial disease often show signs and symptoms uncommon to idiopathic ASD such as cardiac, pancreatic or liver dysfunction, cardiac, growth retardation, fatigability, but in some cases semiology is different. We show two clinical cases of ASD associated to a deficiency of the mitochondrial respiratory chain (complex I+III and IV) with different clinical presentations. In one case, signs and symptoms of mitochondrial disorder were mild and the second diagnosis was attained many years after that of ASD. These findings support the recent growing body of evidence that ASD can be associated with mitochondrial disorder. Children with ASD and abnormal neurologic or systemic findings should be evaluated for mitochondrial disorder.
