Autism spectrum disorder

Autism spectrum disorder (ASD) is a complex neurodevelopmental disorder that affects social interaction, communication, and behavior. It is characterized by a range of symptoms, including repetitive behaviors, impaired social skills, and difficulties with speech and language.

Genetic factors play a significant role in the development of ASD. One gene that has been implicated in the disorder is CTNND2. CTNND2 is a protein-coding gene that is involved in the development and function of synapses, which are the connections between nerve cells. Changes in the CTNND2 gene can lead to alterations in the formation and function of these connections, which may contribute to the development of ASD.
