Labcorp Genetics (formerly Invitae), Labcorp RCV001035940 SCV001199280 likely pathogenic Landau-Kleffner syndrome 2019-11-26 criteria provided, single submitter clinical testing 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. Donor and acceptor splice site variants typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in GRIN2A are known to be pathogenic (PMID: 23933819, 23933820). This variant has not been reported in the literature in individuals with GRIN2A-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change affects an acceptor splice site in intron 4 of the GRIN2A gene. It is expected to disrupt RNA splicing and likely results in an absent or disrupted protein product.
