20. Mutations of the GABRG2 gene may increase the risk of rolandic epilepsy.

Mouse (Murine) gamma-aminobutyric Acid (GABA) A Receptor, gamma 2 (GABRG2) interaction partners

1. deletion of Gabrg2 on dopamine cells induced several behavioral traits associated with high risk of developing alcoholism.

3. The results of this study suggesting that mutations like GABRG2(Q390X) may alter brain thermal regulation and precipitate seizures during temperature elevations.

4. GABAA receptor (GABAAR) and the Na(+)-K(+)-2Cl(-) cotransporter (NKCC1), but not the K(+)-Cl(-) cotransporter (KCC2), were expressed in the terminals of the CRH neurons at the median eminence (ME). In contrast, CRH neuronal somata were enriched with KCC2 but not with NKCC1.

5. This study demonstrated that the reduced local input to fast-spiking interneurons in the somatosensory cortex in the GABAA gamma2 R43Q mouse model of absence epilepsy.

6. Heterozygous Gabrg2(+/Q390X) KI mice are associated with a severe epileptic encephalopathy due to a dominant negative effect of the mutation, while heterozygous Gabrg2(+/-) KO mice are associated with mild absence epilepsy due to simple haploinsufficiency.
