Autism Spectrum Disorder (ASD) is a complex neurodevelopmental condition characterized by challenges with social interaction, communication difficulties, and repetitive behaviors. Autism genetics has occupied researchers’ attention because of how many studies have been done to find out different genes that are assumed to be part of the disorder. On the other hand, genetic research in autism is developing rapidly, and improvements made in this field have resulted in better identification and potential treatment options for autism that provide hope to millions affected.
The Genetic Landscape of Autism
As such, it is widely known that autism has a strong genetic component with numerous genes implicated in its etiology. Studies have implicated mutations in specific genes associated with ASD. For example, hypogammaglobulinemia, sensorimotor deficits, and autistic behaviors resulting from abnormal cerebellum development and loss of GABAergic neurons in the midbrain have been linked to mutations in the PAX5 gene. IGF-1R recycling is regulated by another important gene called GIGYF1. Such disruptions in this gene are attributed to autism social impairments and cognitive deficits.
