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

Verdict is Likely_benign. Variant got -4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.97).
• BP6: Variant 3-11028856-G-T is Benign according to our data. Variant chr3-11028856-G-T is described in ClinVar as [Likely_benign]. Clinvar id is 1546757.Status of the report is criteria_provided_single_submitter, 1 stars.
