Description
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. 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) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on BMPR2 protein function. ClinVar contains an entry for this variant (Variation ID: 212817). This missense change has been observed in individuals with pulmonary arterial hypertension (PMID: 19555857, 20534176, 21737554, 29843651, 31727138, 32581362). This variant is not present in population databases (gnomAD no frequency). This sequence change replaces asparagine, which is neutral and polar, with serine, which is neutral and polar, at codon 126 of the BMPR2 protein (p.Asn126Ser).
