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]

ACMG classification

Verdict is Uncertain_significance. Variant got 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in the BMPR2 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 94 curated pathogenic missense variants (we use a threshold of 10). The gene has 70 curated benign missense variants. Gene score misZ: 2.0624 (below the threshold of 3.09). Trascript score misZ: 3.2701 (above the threshold of 3.09). GenCC associations: The gene is linked to pulmonary hypertension, primary, 1, congenital heart disease, heritable pulmonary arterial hypertension, pulmonary arterial hypertension.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.817
