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 hyperekplexia or congenital stiff-person syndrome. Multiple transcript variants encoding different isoforms have been found. [provided by RefSeq, Dec 2015]

Study found significant associations between the minor alleles of three SNPs (rs2915885, rs11167557, and rs1428159) within the glycine receptor alpha 1 subunit (GLRA1) and dimensional schizotypy, specifically with the disorganized symptoms dimension.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

Status: REVIEWED

Description

Transcript Variant: This variant (3) lacks an internal exon in the 5' region, which results in translation initiation at a downstream AUG start codon, and contains an alternate splice site at the 5' end of the last exon, compared to variant 1. The resulting isoform (3) has a shorter N-terminus and lacks an internal segment in the C-terminal region, compared to isoform 1.
