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]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 4 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), SLC6A1. . Gene score misZ 4.1766 (greater than the threshold 3.09). Trascript score misZ 4.9229 (greater than threshold 3.09). GenCC has associacion of gene with myoclonic-atonic epilepsy, myoclonic-astatic epilepsy.
PP5
Variant 3-11034534-G-A is Pathogenic according to our data. Variant chr3-11034534-G-A is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 421211.We mark this variant Likely_pathogenic, oryginal submissions are: {Uncertain_significance=1, Pathogenic=4}.

Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpNov 02, 2023This sequence change replaces valine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 511 of the SLC6A1 protein (p.Val511Met). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with clinical features of SLC6A1-related conditions (PMID: 29315614, 31302675; Invitae). In at least one individual the variant was observed to be de novo. ClinVar contains an entry for this variant (Variation ID: 421211). 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 with a negative predictive value of 80%. For these reasons, this variant has been classified as Pathogenic. -
