Invitae RCV000631879 SCV000752978 likely pathogenic Long QT syndrome 2017-11-24 criteria provided, single submitter clinical testing This variant is a gross duplication of the genomic region encompassing exons 6-13 of the KCNH2 gene. While the exact position of the duplicated exons cannot be determined from this data, sub-genic duplications are generally in tandem (PMID: 25640679) and may result in an absent or disrupted protein product. This variant has not been reported in the literature in individuals with KCNH2-related disease. Loss-of-function variants in KCNH2 are known to be pathogenic (PMID: 19862833). 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.
