Genes affected

GLRA3 (HGNC:4328): (glycine receptor alpha 3) This gene encodes a member of the ligand-gated ion channel protein family. The encoded protein is a member of the glycine receptor subfamily. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Nov 2013]

Ambry Genetics

Feb 14, 2023

The c.244G>A (p.G82S) alteration is located in exon 3 (coding exon 3) of the GLRA3 gene. This alteration results from a G to A substitution at nucleotide position 244, causing the glycine (G) at amino acid position 82 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
