B6.Grm7em1/Vu

A C57Bl6/J strain contains a Grm7 I154T point mutation. This mutation is clinically associated with a severe neurodevelopmental disorder with profound intellectual disability and seizures. The model is intended to try to mimic these phenotypes in mice and then test if small molecules developed for Grm7 within the Vanderbilt Center for Neuroscience Drug Discovery can correct these deficits.
