Genes affected

NODAL (HGNC:7865): (nodal growth differentiation factor) This gene encodes a secreted ligand of the TGF-beta (transforming growth factor-beta) superfamily of proteins. Ligands of this family bind various TGF-beta receptors leading to recruitment and activation of SMAD family transcription factors that regulate gene expression. The encoded preproprotein is proteolytically processed to generate the mature protein, which regulates early embryonic development. This protein is required for maintenance of human embryonic stem cell pluripotency and may play a role in human placental development. Mutations in this gene are associated with heterotaxy, a condition characterized by random orientation of visceral organs with respect to the left-right axis. [provided by RefSeq, Aug 2016]

The c.658T>C (p.W220R) alteration is located in exon 2 (coding exon 2) of the NODAL gene. This alteration results from a T to C substitution at nucleotide position 658, causing the tryptophan (W) at amino acid position 220 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

ClinVar contains an entry for this variant (Variation ID: 407446). 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 NODAL 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. This variant has not been reported in the literature in individuals affected with NODAL-related conditions. This sequence change replaces tryptophan, which is neutral and slightly polar, with arginine, which is basic and polar, at codon 220 of the NODAL protein (p.Trp220Arg). This variant is present in population databases (rs776168916, gnomAD 0.006%). -
