Invitae RCV000473167 SCV000546558 uncertain significance Beckwith-Wiedemann syndrome 2019-04-13 criteria provided, single submitter clinical testing This sequence change replaces leucine with valine at codon 2533 of the NSD1 protein (p.Leu2533Val). The leucine residue is weakly conserved and there is a small physicochemical difference between leucine and valine. This variant is present in population databases (rs398124386, ExAC 0.008%). This variant has been reported in an individual affected with Sotos syndrome, as well as in the unaffected mother (PMID: 16247291). ClinVar contains an entry for this variant (Variation ID: 96078). 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. In summary, this variant is a rare missense change that is not predicted to affect protein function. It has been reported in the population, in an affected individual and in an unaffected parent, but the available evidence is currently insufficient to determine its role in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
