Variant summary

Our verdict is Likely benign. Variant got -4 ACMG points: 0P and 4B. BS1

This summary comes from the ClinGen Evidence Repository: The BMPR2 c.1766A>G variant is a missense variant predicted to result in a tyrosine to cysteine substitution at amino acid 589 (p.Tyr589Cys). The minor allele frequency in gnomAD v2.1.1 controls at a frequency of 0.001511 (22/14,556 alleles) which is above the cut-off of 0.1% for PAH (BS1 met). The variant is located outside of the critical extracellular and kinase domains of BMPR2 (PM1 not met). The REVEL score is 0.577, not exceeding the threshold of >=0.75 (PP3 not met) or <=0.25 (BP4 not met). No functional data was available and SpliceAI does not predict an effect on splicing. In summary, the variant meets the criteria to be classified as likely benign for pulmonary arterial hypertension based on the ACMG/AMP criteria applied, as specified by the ClinGen Pulmonary Hypertension VCEP: BS1 (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]

Pulmonary hypertension, primary, 1

Uncertain:1Benign:1

Benign, criteria provided, single submitter	clinical testing	Illumina Laboratory Services, Illumina	Nov 21, 2017	This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. The evidence from the literature, in combination with allele frequency data from public databases where available, was sufficient to rule this variant out of causing disease. Therefore, this variant is classified as benign. -
