Genes affected

GABRE (HGNC:4085): (gamma-aminobutyric acid type A receptor subunit epsilon) The product of this gene belongs to the ligand-gated ionic channel (TC 1.A.9) family. It encodes the gamma-aminobutyric acid (GABA) A receptor which is a multisubunit chloride channel that mediates the fastest inhibitory synaptic transmission in the central nervous system. This gene encodes an epsilon subunit. It is mapped to chromosome Xq28 in a cluster comprised of genes encoding alpha 3, beta 4 and theta subunits of the same receptor. Alternatively spliced transcript variants have been identified, but only one is thought to encode a protein. [provided by RefSeq, Oct 2008]

Ambry Genetics

Feb 21, 2024

The c.983G>A (p.R328H) alteration is located in exon 8 (coding exon 8) of the GABRE gene. This alteration results from a G to A substitution at nucleotide position 983, causing the arginine (R) at amino acid position 328 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
