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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 27, 2022The c.1033G>A (p.A345T) 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 1033, causing the alanine (A) at amino acid position 345 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
