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]

Sep 20, 2023

The c.632T>C (p.V211A) alteration is located in exon 6 (coding exon 6) of the GLRA3 gene. This alteration results from a T to C substitution at nucleotide position 632, causing the valine (V) at amino acid position 211 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
