GABRB3 (P28472) variants and mutations

GABRB3 (also known as P28472) is a human protein-coding gene encoding a gamma-aminobutyric acid receptor subunit beta-3 protein. It contributes to inhibitory GABA-A receptor currents in the brain and is particularly important during neurodevelopment. Pathogenic variants can cause developmental and epileptic encephalopathy, while altered dosage within chromosome 15q11-q13 contributes to neurodevelopmental disorders. This analysis covers 888 GABRB3 variants and mutations. Of these, 68% have computational variant effect predictions. Disease context includes developmental and epileptic encephalopathy, 43, epilepsy, and childhood absence epilepsy. Example GABRB3 variants include W2*, W2C, and W2R.
