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]

Variant summary: SLC6A1 c.1738C>T (p.Pro580Ser) results in a non-conservative amino acid change in the encoded protein sequence. Four of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 6.4e-05 in 251212 control chromosomes. c.1738C>T has been reported in the literature in individuals affected with Epilepsy without sufficient evidence for causality (Silva_2024). These report(s) do not provide unequivocal conclusions about association of the variant with Myoclonic-Atonic Epilepsy. At least one publication reports experimental evidence evaluating an impact on protein function. These results showed no damaging effect of this variant (Silva_2024). The following publication has been ascertained in the context of this evaluation (PMID: 38781976). ClinVar contains an entry for this variant (Variation ID: 568080). Based on the evidence outlined above, the variant was classified as likely benign. -

Significance: Likely benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

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. -
