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]

The c.28G>A (p.D10N) alteration is located in exon 3 (coding exon 1) of the SLC6A1 gene. This alteration results from a G to A substitution at nucleotide position 28, causing the aspartic acid (D) at amino acid position 10 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt SLC6A1 protein function. This variant has not been reported in the literature in individuals with SLC6A1-related conditions. This variant is present in population databases (rs751108300, ExAC 0.003%). This sequence change replaces aspartic acid with asparagine at codon 10 of the SLC6A1 protein (p.Asp10Asn). The aspartic acid residue is moderately conserved and there is a small physicochemical difference between aspartic acid and asparagine. -
