Genes affected
CDON (HGNC:17104): (cell adhesion associated, oncogene regulated) This gene encodes a cell surface receptor that is a member of the immunoglobulin superfamily. The encoded protein contains three fibronectin type III domains and five immunoglobulin-like C2-type domains. This protein is a member of a cell-surface receptor complex that mediates cell-cell interactions between muscle precursor cells and positively regulates myogenesis. [provided by RefSeq, Aug 2011]

Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Jan 26, 2024 | This sequence change replaces asparagine, which is neutral and polar, with serine, which is neutral and polar, at codon 294 of the CDON protein (p.Asn294Ser). This variant is present in population databases (rs749949944, gnomAD 0.03%). This variant has not been reported in the literature in individuals affected with CDON-related conditions. ClinVar contains an entry for this variant (Variation ID: 539749). 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 CDON protein function with a negative predictive value of 80%. 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. - |
