Invitae RCV000528016 SCV000652935 uncertain significance Developmental and epileptic encephalopathy, 14; Autosomal dominant nocturnal frontal lobe epilepsy 5 2023-01-24 criteria provided, single submitter clinical testing 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. ClinVar contains an entry for this variant (Variation ID: 473377). This variant has not been reported in the literature in individuals affected with KCNT1-related conditions. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This sequence change creates a premature translational stop signal (p.Arg950*) in the KCNT1 gene. It is expected to result in an absent or disrupted protein product. However, the current clinical and genetic evidence is not sufficient to establish whether loss-of-function variants in KCNT1 cause disease.
