Invitae RCV001041788 SCV001205426 pathogenic Landau-Kleffner syndrome 2019-05-18 criteria provided, single submitter clinical testing 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). For these reasons, this variant has been classified as Pathogenic. This sequence change affects an acceptor splice site in intron 5 of the GRIN2A 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). Disruption of this splice site has been observed to segregate with Landau-Kleffner syndrome in a family (PMID: 23933820).
