Labcorp Genetics (formerly Invitae), Labcorp RCV003232457 SCV002172450 uncertain significance Sotos syndrome 2021-09-02 criteria provided, single submitter clinical testing This sequence change replaces valine with leucine at codon 20 of the NSD1 protein (p.Val20Leu). The valine residue is weakly conserved and there is a small physicochemical difference between valine and leucine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals affected with NSD1-related conditions. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt NSD1 protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
