Mutations or dysregulation of the SLC1A1 gene have been linked to several neurological and psychiatric disorders. For example, alterations in this gene have been associated with schizophrenia, obsessive-compulsive disorder (OCD), and epilepsy. Furthermore, SLC1A1 has been implicated in neurodegenerative diseases like Amyotrophic Lateral Sclerosis (ALS) due to its role in glutamate transport and excitotoxicity.
