GABA-A receptor disorders are caused by variants in one or more of the GABA-A genes.  There are various symptoms of a GABA-A disorder.  These symptoms are not experienced by all individuals. 


Symptoms may include:

  • Developmental delay (including global developmental delay)

  • Epilepsy (including Dravet Syndrome, Lennox-Gastaut Syndrome, and Treatment Resistant Epilepsy)

  • Intellectual disability (mild to severe)

  • Hypotonia

  • Dyspraxia

  • Movement disorders (including dystonia, apraxia, choreoathetosis)

  • Cortical-Visual Impairment

Please see our individual pages for each GABA-A gene under Variants on top menu, for a more specific list of symptoms which have been reported for each gene.
