Marker
Therapy target
| | |
| Gabra5-null mice and alpha5 subunit((H105R)) knock-in mice exhibit signs of hippocampal dysfunction, but are capable of improved performance in several learning and memory tasks | |
in alpha5(H105R) mice a behavioral-cognitive phenotype affecting basal locomotion and the memory for location of objects indicative of hippocampal dysfunction resulting from moderately decreased alpha5-subunit contents |
|
deletion of Gabra5 caused robust autism-like behaviors in mice, including reduced social contacts and vocalizations |
