RCV000442390 | SCV000526885 | likely benign | not specified | 2016-04-27 | criteria provided, single submitter | clinical testing | This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. |
Invitae | RCV000808410 | SCV000948519 | uncertain significance | Koolen-de Vries syndrome | 2018-11-02 | criteria provided, single submitter | clinical testing | This sequence change replaces asparagine with aspartic acid at codon 207 of the KANSL1 protein (p.Asn207Asp). The asparagine residue is highly conserved and there is a small physicochemical difference between asparagine and aspartic acid. This variant is present in population databases (rs372601814, ExAC 0.01%). This variant has not been reported in the literature in individuals with KANSL1-related disease. ClinVar contains an entry for this variant (Variation ID: 385571). 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 tolerated, 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. |
