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
Classification made for transcript
Verdict is Likely_pathogenic. Variant got 9 ACMG points.
PM1
In a hotspot region, there are 2 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 1 benign, 5 uncertain in NM_001204.7
PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant where missense usually causes diseases, BMPR2
PP3
MetaRNN computational evidence supports a deleterious effect, 0.986

Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Oct 31, 2022 | ClinVar contains an entry for this variant (Variation ID: 425844). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt BMPR2 protein function. This missense change has been observed in individual(s) with pulmonary hypertension (Invitae). This variant is not present in population databases (gnomAD no frequency). This sequence change replaces glycine, which is neutral and non-polar, with glutamic acid, which is acidic and polar, at codon 311 of the BMPR2 protein (p.Gly311Glu). - |
