GRIN2B (Glutamate receptor) variants and mutations
GRIN2B (also known as Glutamate receptor) is a human protein-coding gene encoding a glutamate receptor protein. Its annotated function is receptor for glutamate that functions as a ligand-gated ion channel in the central nervous system and plays an important role in excitatory synaptic transmission. L-glutamate acts as an excitatory neurotransmitter at many synapses in the…. It is annotated at the postsynaptic cell membrane. This analysis covers 1 GRIN2B variants and mutations. Disease context includes intellectual disability, autosomal dominant 6, developmental and epileptic encephalopathy, 27, and Alzheimer disease. Example GRIN2B variants include G377R.
