Labcorp Genetics (formerly Invitae), Labcorp RCV001057936 SCV001222463 pathogenic Developmental and epileptic encephalopathy, 14; Autosomal dominant nocturnal frontal lobe epilepsy 5 2019-12-15 criteria provided, single submitter clinical testing For these reasons, this variant has been classified as Pathogenic. This sequence change affects a donor splice site in intron 25 of the KCNT1 gene. It is expected to disrupt RNA splicing and likely results in an absent or disrupted protein product. This variant is not present in population databases (ExAC no frequency). This variant has been observed in individual(s) with KCNT1-related disease (Invitae). In at least one individual the variant was observed to be de novo. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site, but this prediction has not been confirmed by published transcriptional studies.
