Genes affected

GABRG1 (HGNC:4086): (gamma-aminobutyric acid type A receptor subunit gamma1) The protein encoded by this gene belongs to the ligand-gated ionic channel family. It is an integral membrane protein and plays an important role in inhibiting neurotransmission by binding to the benzodiazepine receptor and opening an integral chloride channel. This gene is clustered with three other family members on chromosome 4. [provided by RefSeq, Jul 2008]

The c.1233T>G (p.D411E) alteration is located in exon 9 (coding exon 9) of the GABRG1 gene. This alteration results from a T to G substitution at nucleotide position 1233, causing the aspartic acid (D) at amino acid position 411 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
