Function

The inhibitory glycine receptor mediates postsynaptic inhibition in the spinal cord and other regions of the central nervous system. It is a pentameric receptor composed solely of alpha subunits. The GLRB gene encodes the alpha subunit of the receptor.[7]

Clinical significance

Mutations in the gene have been associated with hyperekplexia, a neurologic syndrome associated with an exaggerated startle reaction.[8][9]
