Invitae RCV000644672 SCV000766375 uncertain significance Koolen-de Vries syndrome 2017-12-28 criteria provided, single submitter clinical testing This sequence change replaces threonine with asparagine at codon 184 of the KANSL1 protein (p.Thr184Asn). The threonine residue is highly conserved and there is a small physicochemical difference between threonine and asparagine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with KANSL1-related disease. Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C15"). 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.
