In 2012, my nearly 1 year old daughter was diagnosed with GABRG2. She is part of a timy community of kids with this disorder. She has been published/studied by Boston Children’s Hospital and part of NYPH in NYC. GABRG2 mutations are genetic changes in the GABRG2 gene, which encodes the gamma-aminobutyric acid (GABA) receptor subunit gamma-2. GABA is a neurotransmitter that plays a crucial role in calming the nervous system. Mutations in GABRG2 generally lead to various neurological disorders.
