Complex IV‐mediated dysfunction of parvalbumin+ interneurons may also underlie the vulnerability and impairment of these interneurons in other neurodevelopmental disorders associated with mitochondrial dysfunction, including autism spectrum disorder (ASD) and schizophrenia [46, 47, 48] and may also explain why epilepsy is a common comorbidity of these disorders [49, 50]. The gene discussed is PVALB; the disease is epilepsy.
