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 7 ACMG points.

• PM1: In a hotspot region, there are 4 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 2 uncertain in NM_001204.7
• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), BMPR2. . Gene score misZ 2.0624 (greater than the threshold 3.09). Trascript score misZ 3.2701 (greater than threshold 3.09). GenCC has associacion of gene with pulmonary hypertension, primary, 1, congenital heart disease, heritable pulmonary arterial hypertension, pulmonary arterial hypertension.
• PP3: No computational evidence supports a deleterious effect, but strongly conserved according to phyloP
• PP5: Variant 2-202532727-TCCCAG-CGGAGA is Pathogenic according to our data. Variant chr2-202532727-TCCCAG-CGGAGA is described in ClinVar as [Pathogenic]. Clinvar id is 425909.Status of the report is no_assertion_criteria_provided, 0 stars.
