Genes affected
GABRR3 (HGNC:17969): (gamma-aminobutyric acid type A receptor subunit rho3) The neurotransmitter gamma-aminobutyric acid (GABA) functions in the central nervous system to regulate synaptic transmission of neurons. This gene encodes one of three related subunits, which combine as homo- or hetero-pentamers to form GABA(C) receptors. In humans, some individuals contain a single-base polymorphism (dbSNP rs832032) that is predicted to inactivate the gene product. [provided by RefSeq, Jan 2012]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 05, 2023The c.605T>A (p.L202Q) alteration is located in exon 6 (coding exon 5) of the GABRR3 gene. This alteration results from a T to A substitution at nucleotide position 605, causing the leucine (L) at amino acid position 202 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
