Variants with ambiguous mapping are still reported relative to the KANSL1 transcript. Until the location of this sequence change can be resolved, the clinical significance of this variant remains uncertain. It has been classified as a Variant of Uncertain Significance. 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. ClinVar contains an entry for this variant (Variation ID: 935643). This variant has not been reported in the literature in individuals with KANSL1-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces aspartic acid, which is acidic and polar, with valine, which is neutral and non-polar, at codon 216 of the KANSL1 protein (p.Asp216Val). |
