OMIM: 614619
Orphanet: ORPHA3197


glycine receptor β subunit
Comments:  Human hyperekplexia is caused by simultaneous occurrence on separate alleles of a GlyR β subunit missense mutation (G229D) that modestly reduces the glycine sensitivity of α1β GlyRs and a β subunit splice variant that excises exon 5. When present on a single allele, the individual mutations result in no phenotype.
