Genes affected

GABRR1 (HGNC:4090): (gamma-aminobutyric acid type A receptor subunit rho1) GABA is the major inhibitory neurotransmitter in the mammalian brain where it acts at GABA receptors, which are ligand-gated chloride channels. GABRR1 is a member of the rho subunit family. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Feb 2012]

Ambry Genetics

Apr 01, 2024

The c.1348A>T (p.I450F) alteration is located in exon 10 (coding exon 10) of the GABRR1 gene. This alteration results from a A to T substitution at nucleotide position 1348, causing the isoleucine (I) at amino acid position 450 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
