Description

This variant disrupts the p.Cys117 amino acid residue in BMPR2. Other variant(s) that disrupt this residue have been observed in individuals with BMPR2-related conditions (PMID: 21737554, 29650961), which suggests that this may be a clinically significant amino acid residue. For these reasons, this variant has been classified as Pathogenic. Experimental studies have shown that this missense change affects BMPR2 function (PMID: 12045205). This sequence change replaces cysteine, which is neutral and slightly polar, with tyrosine, which is neutral and polar, at codon 117 of the BMPR2 protein (p.Cys117Tyr). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individuals with pulmonary artery hypertension (PMID: 11015450, 27884767, 29631995; Invitae). ClinVar contains an entry for this variant (Variation ID: 425766). 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.
