GeneDx RCV000760460 SCV000890347 pathogenic not provided 2019-01-11 criteria provided, single submitter clinical testing The R444X nonsense variant in the TBK1 gene has been reported previously in association with ALS with and without FTLD (Black et al., 2017; Tsai et al., 2016). In vitro functional studies shower lower protein expression and loss of kinase activity (Tsai et al., 2016). The R444X variant is predicted to result in nonsense-mediated mRNA decay or protein truncation. In vitro functional studies indicate that the truncated protein lacked kinase activity (Tsai et al., 2016). This variant is not observed in large population cohorts (Lek et al., 2016). Based on the currently available clinical and molecular information, we interpret R444X as a pathogenic variant.
