Invitae | RCV000644670 | SCV000766373 | uncertain significance | Koolen-de Vries syndrome | 2021-09-03 | 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. Variants with ambiguous mapping are still reported relative to the KANSL1 transcript. This sequence change replaces serine with isoleucine at codon 386 of the KANSL1 or 17q21.31 segmental duplication protein (p.Ser386Ile). The serine residue is highly conserved and there is a large physicochemical difference between serine and isoleucine. 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: 536295). 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. 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. |
