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 NM_001204.7(BMPR2):c.2948G>A variant is a missense variant predicted to cause substitution of arginine to glutamine at amino acid position 983 (p.Arg983Gln). The highest population minor allele frequency in gnomAD v2.1.1 controls is 0.0034 (8/2358) in the Ashkenazi Jew population, which is higher than the ClinGen PH VCEP threshold (>0.1%) for BS1, and therefore meets this criterion (BS1). The computational predictor REVEL gives a score of 0.4, which is neither above nor below the thresholds predicting a damaging or benign impact on BMPR2 function. In summary, this 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.

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]

Uncertain significance, criteria provided, single submitter	clinical testing	Centre for Mendelian Genomics, University Medical Centre Ljubljana	Jan 01, 2016	This variant was classified as: Uncertain significance. -
Benign, criteria provided, single submitter	clinical testing	Illumina Laboratory Services, Illumina	Jan 13, 2018	This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. -

The BMPR2 c.2948G>A; p.Arg983Gln variant (rs148099152) is reported in ClinVar (Variation ID: 333652), and in the literature in an individual of Ashkenazi Jewish descent affected with pulmonary arterial hypertension (Newman 2004). However, this variant is found in the Ashkenazi Jewish population with an allele frequency of 0.46% (48/10366 alleles) in the Genome Aggregation Database, suggesting that it may be a polymorphism in this population. The arginine at codon 983 is highly conserved, and computational analyses (SIFT: damaging, PolyPhen-2: benign) predict conflicting effects of this variant on protein structure/function. Due to limited information, the clinical significance of the p.Arg983Gln variant is uncertain at this time. References: Newman JH et al. Genetic basis of pulmonary arterial hypertension: current understanding and future directions. J Am Coll Cardiol. 2004 Jun 16;43(12 Suppl S):33S-39S. -
