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]

SLC6A1-AS1 (HGNC:40546): (SLC6A1 antisense RNA 1)

ACMG classification

Verdict is Benign. Variant got -9 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.36).
• BP6: Variant 3-11017223-C-T is Benign according to our data. Variant chr3-11017223-C-T is described in ClinVar as [Likely_benign]. Clinvar id is 1604984.Status of the report is criteria_provided_single_submitter, 1 stars.
• BP7: Synonymous conserved (PhyloP=-0.939 with no splicing effect.
• BS2: High AC in GnomAdExome4 at 22 AD gene.
