Invitae RCV000015316 SCV001223220 pathogenic Frontotemporal dementia 2019-04-19 criteria provided, single submitter clinical testing This sequence change replaces arginine with tryptophan at codon 406 of the MAPT protein (p.Arg406Trp). The arginine residue is highly conserved and there is a moderate physicochemical difference between arginine and tryptophan. This variant is present in population databases (rs63750424, ExAC 0.002%). This variant has been observed in many individuals affected with behavioral variant frontotemporal dementia (bvFTD), Alzheimer's disease and mixed dementia with parkinsonism and has been observed to segregate with disease in many families (PMID: 9382467, 23727082, 26028272, 11117542, 11889249, 23383383, 25942996, 9641683). ClinVar contains an entry for this variant (Variation ID: 14247). This variant has been reported to affect MAPT protein function (PMID: 19304664, 21339331, 11756436, 11102510, 24150109, 10797541). For these reasons, this variant has been classified as Pathogenic.
GeneDx RCV000084554 SCV001781734 pathogenic not provided 2021-09-02 criteria provided, single submitter clinical testing Published functional studies demonstrate that R406W cells show a decreased level of phosphorylation and are unable to bind to microtubules resulting in accumulation in the cytoplasm (Perez et al., 2000; Delobel et al., 2002).; In silico analysis, which includes protein predictors and evolutionary conservation, supports a deleterious effect; This variant is associated with the following publications: (PMID: 33061333, 30924900, 30562452, 31836585, 31127772, 29370822, 30279455, 23727082, 20683187, 18587238, 10514099, 14517953, 9641683, 18284428, 11889249, 12368474, 11278002, 29253099, 25942996, 26734663, 25377499, 26028272, 26581847, 20377816, 22787795, 21849646, 18992292, 11102510, 21339331, 23105105, 19304664, 11756436, 23338682, 20634584, 24150109, 10820221, 18803694, 22368988, 23383383)
