Genes affected

SLC6A11 (HGNC:11044): (solute carrier family 6 member 11) The protein encoded by this gene is a sodium-dependent transporter that uptakes gamma-aminobutyric acid (GABA), an inhibitory neurotransmitter, which ends the GABA neurotransmission. Defects in this gene may result in epilepsy, behavioral problems, or intellectual problems. Two transcript variants encoding different isoforms have been found for this gene.

Ambry Genetics

May 27, 2022

The c.766G>T (p.V256L) alteration is located in exon 6 (coding exon 6) of the SLC6A11 gene. This alteration results from a G to T substitution at nucleotide position 766, causing the valine (V) at amino acid position 256 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
