Invitae RCV001904856 SCV002126841 uncertain significance Koolen-de Vries syndrome 2021-10-14 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 variant, c.808_816del, results in the deletion of 3 amino acid(s) of the KANSL1 protein (p.Leu270_Ser272del), but otherwise preserves the integrity of the reading frame. 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. Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. 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.
