Labcorp Genetics (formerly Invitae), Labcorp RCV003615392 SCV004540502 uncertain significance Spondylocostal dysostosis 3, autosomal recessive 2023-07-28 criteria provided, single submitter clinical testing This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 286 of the LFNG protein (p.Arg286Trp). This variant is present in population databases (rs752671299, gnomAD 0.006%). This missense change has been observed in individual(s) with clinical features of spondylocostal dysostosis (Invitae). 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 LFNG 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.
