BMPR2
protein-codingbone morphogenetic protein receptor type 2, the group of Type 2 receptor serine/threonine kinases
Gene summary
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]

BMPR2 was first reported in relation to autosomal dominant pulmonary arterial hypertension in 2000 (Deng et al PMID:10903931 and The International PPH Consortium PMID:10973254). More than 500 unique variants (missense, in-frame indel, nonsense, frameshift, large deletions) have been reported in humans. Evidence supporting this gene-disease relationship includes case-level, case-control, segregation and experimental data. Summary of case-level data: 12 points. Variants in this gene have been reported in at least 16 probands in 2 publications (PMID:10903931, PMID:10973254). Variants in this gene segregated with disease in 10 additional family members. More evidence is available in the literature but the maximum score for genetic evidence (12 points) has been reached. The mechanism is haploinsufficiency (PMID:11115378, PMID: 16429395). Summary of experimental data: 6 points. This gene-disease association is supported by expression, biochemical, in vitro functional and animal model data. In summary, BMPR2 is definitively associated with autosomal dominant pulmonary arterial hypertension. This has been repeatedly demonstrated in both research and diagnostic settings, and has been upheld over time. This classification was approved by the ClinGen PH Working Group on Sept 9, 2020.

*BMPR2* was first reported in relation to autosomal dominant congenital heart disease in 2016 (Liu et al., PMID: 27002414; Sicko et al., PMID: 27788187). Another publication in 2012 reported a paternally inherited deletion at 2q33.1 of about 34 kb, falling into the first intron of the *BMPR2* (PMID: 21457232). Per criteria outlined by the ClinGen Lumping and Splitting Working Group, we found no difference in molecular mechanism, inheritance pattern, and phenotypic variability. Therefore, congenital heart disease, Ebstein anomaly, and conotruncal defects have been lumped into one disease entity. One proband with a noncanonical splice-site variant is included in this curation (PMID: 27002414). At least eight other unique variants (missense, frameshifts, splice site) reported in five probands in five publications were not scored due to their high minor allele frequency (> 0.00001) in gnomAD v2.1.1 or a low REVEL score (PMIDs: 27788187, 27002414, 28991257, 33448881, 35910219). The gene-disease relationship is supported by two mouse models and expression data (PMIDs: 23352489, 12441304, 19409885). In summary, there is limited evidence to support this gene-disease relationship. Although more evidence is needed to support a causal role, no convincing evidence has emerged that contradicts the gene-disease relationship. Of note, *BMPR2* has been classified as definitive for autosomal dominant pulmonary arterial hypertension by the Pulmonary Hypertension GCEP in December 2020. This classification was approved by the ClinGen Congenital Heart Disease GCEP on the meeting date 9/11/2023 (SOP Version 9).

Rationale: While prognosis is overall poor, medical therapy (eg, with calcium antagonists, anticoagulants, prostanoids, endothelin receptor antagonists, etc.) may be beneficial, though heart/lung transplantation may be required; Control of complications may be beneficial; Exposure to agents such as fenfluramine has been described as greatly increasing the risk of disease

ClinVar Variants & Pathogenicity by Type
Statistics based on transcript NM_001204.7. Only rare variants are included.
We include only reliable ClinVar variants with their consequences to MANE Select, MANE Plus Clinical transcripts, or transcripts with TSL equal to 1. Click a count to filter the variants table below.
Slight differences between displayed counts and ClinVar may occur due to a different transcript/consequence chosen by our variant effect predictor, or because we classify Benign/Likely benign as Likely benign and Pathogenic/Likely pathogenic as Likely pathogenic.

- Function
- FUNCTION: On ligand binding, forms a receptor complex consisting of two type II and two type I transmembrane serine/threonine kinases. Type II receptors phosphorylate and activate type I receptors which autophosphorylate, then bind and activate SMAD transcriptional regulators. Binds to BMP7, BMP2 and, less efficiently, BMP4. Binding is weak but enhanced by the presence of type I receptors for BMPs. Mediates induction of adipogenesis by GDF6. {ECO:0000250|UniProtKB:O35607}.;
- Disease
- DISEASE: Pulmonary venoocclusive disease 1, autosomal dominant (PVOD1) [MIM:265450]: A disease characterized by widespread fibrous obstruction and intimal thickening of septal veins and preseptal venules, a low diffusing capacity for carbon monoxide, occult alveolar hemorrhage, and nodular ground-glass opacities, septal lines and lymph node enlargement showed by high-resolution computed tomography of the chest. It is frequently associated with pulmonary capillary dilatation and proliferation, and is a rare and devastating cause of pulmonary hypertension. {ECO:0000269|PubMed:12446270, ECO:0000269|PubMed:16429395}. Note=The disease is caused by mutations affecting the gene represented in this entry.;
