Invitae | RCV000696346 | SCV000824903 | uncertain significance | Koolen-de Vries syndrome | 2020-06-27 | criteria provided, single submitter | clinical testing | Due to the possible presence of a polymorphic segmental duplication, the location of the variant could not be unambiguously resolved. If the variant occurs in the KANSL1 gene, this sequence change replaces asparagine with serine at codon 41 of the KANSL1 protein (p.Asn41Ser). The asparagine residue is highly conserved and there is a small physicochemical difference between asparagine and serine. The frequency data for this variant in the population databases (ExAC) is considered unreliable due to the presence of homologous sequence, such as pseudogenes or paralogs, in the genome. This variant has not been reported in the literature in individuals with KANSL1-related conditions. ClinVar contains an entry for this variant (Variation ID: 205765). 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. 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. |
