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 Likely_pathogenic. Variant got 6 ACMG points.

• PM1: In a topological_domain Extracellular (size 123) in uniprot entity BMPR2_HUMAN there are 39 pathogenic changes around while only 10 benign (80%) in NM_001204.7
• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant where missense usually causes diseases, BMPR2
• PP5: Variant 2-202464872-G-A is Pathogenic according to our data. Variant chr2-202464872-G-A is described in ClinVar as [Pathogenic]. Clinvar id is 425707.Status of the report is no_assertion_criteria_provided, 0 stars.
