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]

Aug 12, 2021

The c.1211A>G (p.N404S) alteration is located in exon 10 (coding exon 10) of the GLRA3 gene. This alteration results from a A to G substitution at nucleotide position 1211, causing the asparagine (N) at amino acid position 404 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
