GABRE
Chr Xgamma-aminobutyric acid type A receptor subunit epsilon
The epsilon subunit of GABA-A receptors forms part of heteropentameric chloride channels that mediate fast inhibitory neurotransmission in the brain and allow spontaneous chloride channel activity. Mutations cause early infantile epileptic encephalopathy and Ohtahara syndrome with X-linked inheritance. This gene shows low constraint to loss-of-function variants, and phenotypes may include both neurological and cardiac manifestations.

Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Highly tolerant — LoF variants common in population
Tolerant to missense variation
This gene has evidence for multiple mechanisms of pathogenicity (dominant-negative and gain-of-function). Both the Badonyi & Marsh prediction and the broader genomic evidence point to dominant-negative as the predominant mechanism. Different variants in this gene may act through different mechanisms — interpret in context of the specific variant.
Note: In-silico variant effect predictors (SIFT, PolyPhen, REVEL, CADD) may underestimate pathogenicity of missense variants in genes with GOF or DN mechanisms. Consider functional evidence and clinical context.
