RCV003509616 | SCV004297295 | likely pathogenic | Brugada syndrome 5 | 2023-12-12 | criteria provided, single submitter | clinical testing | The SCN1B gene has multiple clinically relevant transcripts. This variant occurs in alternate transcript NM_001037.5 and corresponds to NM_199037.3:c.*5017A>G in the primary transcript. This sequence change affects an acceptor splice site in intron 3 of the SCN1B gene. It is expected to disrupt RNA splicing. Variants that disrupt the donor or acceptor splice site typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in SCN1B are known to be pathogenic (PMID: 17629415, 30660056). This variant is not present in population databases (gnomAD no frequency). Disruption of this splice site has been observed in individual(s) with clinical features of autosomal dominant generalized epilepsy with febrile seizures (PMID: 29655203; Invitae). This variant has been reported in individual(s) with autosomal recessive developmental and epileptic encephalopathy (PMID: 28218389); however, the role of the variant in this condition is currently unclear. In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. |
