Invitae RCV000558536 SCV000652926 uncertain significance Developmental and epileptic encephalopathy, 14; Autosomal dominant nocturnal frontal lobe epilepsy 5 2023-12-01 criteria provided, single submitter clinical testing This variant, c.2061_2066del, results in the deletion of 2 amino acid(s) of the KCNT1 protein (p.Gly691_Gly692del), but otherwise preserves the integrity of the reading frame. This variant is present in population databases (rs754629346, gnomAD 0.007%). This variant has been observed in individual(s) with frontal lobe epilepsy (PMID: 32086284). ClinVar contains an entry for this variant (Variation ID: 473368). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.

PreventionGenetics, part of Exact Sciences RCV003409815 SCV004113984 uncertain significance KCNT1-related disorder 2023-06-14 criteria provided, single submitter clinical testing The KCNT1 c.2061_2066del6 variant is predicted to result in an in-frame deletion (p.Gly691_Gly692del). This variant was reported in an individual with frontal lobe epilepsy (Krenn et al 2020. PubMed ID: 32086284). This variant is reported in 0.0092% of alleles in individuals of European (Non-Finnish) descent in gnomAD ( At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence.
