Invitae RCV000015322 SCV000832815 pathogenic Frontotemporal dementia 2019-03-30 criteria provided, single submitter clinical testing This sequence change replaces asparagine with lysine at codon 279 of the MAPT protein (p.Asn279Lys). The asparagine residue is highly conserved and there is a moderate physicochemical difference between asparagine and lysine. This variant is not present in population databases (ExAC no frequency). This variant has been observed to segregate with frontotemporal dementia in several families (PMID: 9789048, 10412802, 10802785, 22818528, 26295349), and has also been observed in additional individuals affected with frontotemporal dementia (PMID: 10489057, 14568818, 27082848). ClinVar contains an entry for this variant (Variation ID: 14253). Experimental studies have shown that this variant affects splicing, leading to altered MAPT isoform ratio (PMID: 10412802, 16219306, 17715352, 19498037, 26143746, 26220942, 26373282). Mouse models recapitulate the human frontotemporal dementia phenotype (PMID: 16219306, 17715352, 22169201). For these reasons, this variant has been classified as Pathogenic.
