Identification and Classification of Position-specific GABA_A Receptor Subunit Missense Variants for Their Role In Hippocampal Pyramidal Neurons

Overview

This study introduces a multiscale framework, spanning from DNA to protein function and neural behavior. It presents a novel approach for investigating predicted pathogenic mutations in the GABA A receptor subunit, hypothesizing that epileptogenic mutations and proximal mutations, predicted as pathogenic, may produce similar effects on the CA1 pyramidal neuron model.
