Entrez ID	2741
Gene name	Glycine receptor alpha 1
Gene symbol	GLRA1
Synonyms (NCBI Gene)	HKPX1STHE
Chromosome	5
Chromosome location	5q33.1
Summary	The protein encoded by this gene is a subunit of a pentameric inhibitory glycine receptor, which mediates postsynaptic inhibition in the central nervous system. Defects in this gene are a cause of startle disease (STHE), also known as hereditary hyperekpl
