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]

Lurie Children's Hospital of Chicago	Mar 30, 2021	SLC6A1 NM_003042.3 exon 12 p.Arg417His (c.1250G>A): This variant has not been reported in the literature but is present in 0.02% (9/34294) of Latino alleles in the Genome Aggregation Database (http://gnomad.broadinstitute.org/variant/3-11070965-G-A). This variant is present in ClinVar (Variation ID:475469). Evolutionary conservation and computational predictive tools for this variant are unclear. In summary, data on this variant is insufficient for disease classification. Therefore, the clinical significance of this variant is uncertain. -

Ambry Genetics

Jan 28, 2019

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
