Genes affected

SLC6A1 (HGNC:11042): (solute carrier family 6 member 1) The protein encoded by this gene is a gamma-aminobutyric acid (GABA) transporter that localizes to the plasma membrane. The encoded protein removes GABA from the synaptic cleft, restoring it to presynaptic terminals. [provided by RefSeq, Jan 2017]

Myoclonic-astatic epilepsy

Uncertain significance, criteria provided, single submitter	clinical testing	New York Genome Center	Feb 11, 2021	The c.31G>A(p.Gly11Arg) missense variant in exon 3 of 16 of SLC6A1 has not been reported in affected individuals in the available literature. This variant is seen at a very low frequency in in gnomADv3 (4 heterozygotes, allele frequency =0.00002632, no homozygotes) indicating it is not a common benign variant in the populations represented in this database. In silico predictors suggest this variant is benign (REVEL; score:0.4429) and tolerated (SIFT; score:0.17). Given the lack of inheritance data and functional studies supporting its pathogenicity, the c.31G>A(p.Gly11Arg) variant identified in the SLC6A1 gene is reported here as a Variant of Uncertain Significance. -

The p.G11R variant (also known as c.31G>A), located in coding exon 1 of the SLC6A1 gene, results from a G to A substitution at nucleotide position 31. The glycine at codon 11 is replaced by arginine, an amino acid with dissimilar properties. This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
