Genes affected

GABRP (HGNC:4089): (gamma-aminobutyric acid type A receptor subunit pi) The gamma-aminobutyric acid (GABA) A receptor is a multisubunit chloride channel that mediates the fastest inhibitory synaptic transmission in the central nervous system. The subunit encoded by this gene is expressed in several non-neuronal tissues including the uterus and ovaries. This subunit can assemble with known GABA A receptor subunits, and the presence of this subunit alters the sensitivity of recombinant receptors to modulatory agents such as pregnanolone. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, May 2014]

Collection Method: clinical testing

The c.309G>C (p.K103N) alteration is located in exon 5 (coding exon 4) of the GABRP gene. This alteration results from a G to C substitution at nucleotide position 309, causing the lysine (K) at amino acid position 103 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
