Variant summary

Our verdict is Uncertain significance. The variant received 2 ACMG points: 2P and 0B. PM2

This summary comes from the ClinGen Evidence Repository: The BMPR2 c.797G>C variant is a missense variant predicted to cause an arginine to threonine substitution at amino acid 266 (p.Arg266Thr). The variant is absent from gnomAD v2.1.1 controls and v4.1 (PM2 met). The REVEL score is 0.628 and does not meet PP3 (≥0.75) nor BP4 (<0.25) criteria for computational predicted impact on the gene product. Two unrelated idiopathic pulmonary arterial hypertension probands have been reported (PMID:16429395, PMID:19555857) but is below the threshold for PP1 (at least three probands). An additional proband with pulmonary arterial hypertension associated with another disease (PMID:31727138) was not included in the count. Experimental data has not been reported for this variant. In summary, this variant is classified as a variant of uncertain significance for pulmonary arterial hypertension based on the ACMG/AMP criteria applied, as specified by the ClinGen Pulmonary Hypertension VCEP: PM2 (VCEP specifications version 1.1, 1/18/2024).

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]
