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]

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 09, 2024The c.115T>C (p.S39P) alteration is located in exon 2 (coding exon 2) of the GLRA2 gene. This alteration results from a T to C substitution at nucleotide position 115, causing the serine (S) at amino acid position 39 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
