Invitae RCV001222588 SCV001394693 likely pathogenic Beckwith-Wiedemann syndrome 2019-06-19 criteria provided, single submitter clinical testing This sequence change replaces cysteine with glycine at codon 2070 of the NSD1 protein (p.Cys2070Gly). The cysteine residue is highly conserved and there is a large physicochemical difference between cysteine and glycine. This variant is not present in population databases (ExAC no frequency). This variant has been observed to be de novo in an individual with clinical features of Sotos syndrome (Invitae). 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, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic.
