Genes affected

BMPR2 (HGNC:1078): (bone morphogenetic protein receptor type 2) This gene encodes a member of the bone morphogenetic protein (BMP) receptor family of transmembrane serine/threonine kinases. The ligands of this receptor are members of the TGF-beta superfamily. BMPs are involved in endochondral bone formation and embryogenesis. These proteins transduce their signals through the formation of heteromeric complexes of two different types of serine (threonine) kinase receptors: type I receptors of about 50-55 kD and type II receptors of about 70-80 kD. Mutations in this gene have been associated with primary pulmonary hypertension, both familial and fenfluramine-associated, and with pulmonary venoocclusive disease. [provided by RefSeq, May 2020]

The BMPR2 c.1516A>G variant is a missense variant predicted to cause substitution of methionine to valine at amino acid position 506 ((p.(Met506Val)). The highest population minor allele frequency is for East Asian (0.00022) in gnomAD v2.1.1 controls and 0.00015 in gnomAD v3.1.2 and does not meet population criteria (PM2 <0.01%, BS1 >0.1%, anBA1 >1%). BP4 is met by the computational predictor REVEL score of 0.23, which is below the PH-VCEP specified threshold of <0.25 (additional support for BP4 is alpha missense score of 0.077). This variant does not reside within the critical extracellular or kinase domains, so PM1 is not met. Co-segregation/case and experimental criteria was not evaluated due to lack of reported evidence. Alternative variants in the same amino acid have not been reported. In summary, this variant meets the criteria to be classified as a variant of uncertain significance (VUS) for pulmonary arterial hypertension based on the ACMG/AMP criteria applied, as specified by the ClinGen Pulmonary Hypertension VCEP: BP4 (VCEP specification version 1.1, 1/18/2024). -

This BMPR2 variant (rs370457339) is rare (<0.1%) in a large population dataset (gnomAD: 11/251490 total alleles; 0.004%; no homozygotes) and has not been reported in the literature, to our knowledge. This variant has been reported in ClinVar. Three bioinformatic tools queried predict that this substitution would be tolerated, and the methionine residue at this position is evolutionarily conserved across most mammals. Due to insufficient evidence, we consider the clinical significance of c.1516A>G to be uncertain at this time. -
