Invitae RCV000650260 SCV000772100 pathogenic Grn-related frontotemporal lobar degeneration with Tdp43 inclusions; Ceroid lipofuscinosis, neuronal, 11 2017-08-11 criteria provided, single submitter clinical testing This sequence change affects an acceptor splice site in intron 11 of the GRN 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 reported to segregate with frontotemporal dementia(FTD) in a single family and reported in an individual with FTD (PMID: 20142524, 21482928). Donor and acceptor splice site variants typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in GRN are known to be pathogenic (PMID: 16862116, 16950801, 22608501). Experimental studies have shown that this splice acceptor change resulted in partial reduction in splice site (PMID: 20142524). For these reasons, this variant has been classified as Pathogenic.
