ARUP Laboratories, Molecular Genetics and Genomics, ARUP Laboratories RCV000197776 SCV000885066 pathogenic not provided 2018-04-11 criteria provided, single submitter clinical testing The BMPR2 c.631C>T; p.Arg211Ter variant (rs137852753) has been described in several individuals affected with familial and sporadic pulmonary hypertension (Humbert 2002, Machado 2001, Machado 2006, Portillo 2010, Sztrymf 2008, Thomson 2000). It has been reported as pathogenic by several laboratories in ClinVar (Variation ID: 8812) and is absent from general population databases (1000 Genomes Project, Exome Variant Server, and Genome Aggregation Database), indicating it is not a common polymorphism. This variant induces an early termination codon and is predicted to result in a truncated protein or mRNA subject to nonsense-mediated decay. Based on available information, this variant is considered pathogenic. References: Humbert M et al. BMPR2 germline mutations in pulmonary hypertension associated with fenfluramine derivatives.

GeneDx RCV000197776 SCV000249640 pathogenic not provided 2017-02-07 criteria provided, single submitter clinical testing The R211X variant in the BMPR2 gene has been reported in individuals with familial PAH as well as in families with sporadic idopathic PAH, and was absent from greater than 260 control chromosomes (Cogen et al., 2006; Elliot et al., 2006; Humbert et al, 2002; Machado et al., 2001; Machado et al., 2009; Pfarr et al., 2011; Portillo et al, 2010; Thompson et al., 2000). R211X is predicted to cause loss of normal protein function either by protein truncation or nonsense-mediated mRNA decay. Other nonsense variants in the BMPR2 gene have been reported in association with PAH. In summary, R211X in the BMPR2 gene is interpreted as a disease-causing variant.
Invitae RCV000009357 SCV000629982 pathogenic Primary pulmonary hypertension 2017-03-03 criteria provided, single submitter clinical testing This sequence change creates a premature translational stop signal at codon 211 (p.Arg211*) of the BMPR2 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in BMPR2 are known to be pathogenic. This particular variant has been reported in the literature in several individuals with pulmonary arterial hypertension (PMID: 11015450, 19555857, 20534176). ClinVar contains an entry for this variant (Variation ID: 8812). For these reasons, this variant has been classified as Pathogenic.
