Variant summary

Our verdict is Uncertain significance. The variant received 3 ACMG points: 4P and 1B. PM1 PM2 BP6

The NM_003042.4(SLC6A1):​c.152T>A​(p.Phe51Tyr) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. F51L) has been classified as Uncertain significance.

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

Our verdict: Uncertain_significance. The variant received 3 ACMG points.

• PM1: In a hotspot region, there are 8 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 7 benign, 12 uncertain in NM_003042.4
• PM2: Very rare variant in population databases, with high coverage
• BP6: Variant 3-11017363-T-A is Benign according to our data. Variant chr3-11017363-T-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 475474.
