Invitae RCV000652438 SCV000774308 uncertain significance Congenital sideroblastic anemia-B-cell immunodeficiency-periodic fever-developmental delay syndrome 2018-11-08 criteria provided, single submitter clinical testing This sequence change replaces isoleucine with threonine at codon 78 of the TRNT1 protein (p.Ile78Thr). The isoleucine residue is weakly conserved and there is a moderate physicochemical difference between isoleucine and threonine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with TRNT1-related disease. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
