Variant summary

Our verdict is Uncertain significance. The variant received 4 ACMG points: 4P and 0B. PM1 PP3 PM2_Supporting

This summary comes from the ClinGen Evidence Repository: This BMPR2 missense variant c.932G>A is predicted to change a glycine residue to a glutamic acid at position 311. This change occurs in the kinase domain, which is a well established functional domain (PM1 is met). It is absent from gnomAD v2.1.1 controls and gnomAD v4.1 (PM2_supporting is met). There are two ClinVar submissions for this variant, but the affected status of one is "unknown" (PS4 not met). Computational evidence for pathogenicity as evaluated by REVEL generated a score of 0.979 indicating that PP3 is met based on the threshold specified by the PH-VCEP >0.75.In summary, the variant meets the criteria to be classified as variant of uncertain significance (VUS) for pulmonary arterial hypertension based on the ACMG/AMP criteria applied, as specified by the ClinGen Pulmonary Hypertension VCEP: PM1, PM2_Supp, PP3 (VCEP specification 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]
