Genes affected
GLRA2 (HGNC:4327): (glycine receptor alpha 2) The glycine receptor consists of two subunits, alpha and beta, and acts as a pentamer. The protein encoded by this gene is an alpha subunit and can bind strychnine. Several transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Jan 2010]

Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Mar 15, 2024 | The c.191C>A (p.P64Q) alteration is located in exon 2 (coding exon 2) of the GLRA2 gene. This alteration results from a C to A substitution at nucleotide position 191, causing the proline (P) at amino acid position 64 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
