The BMPR2 c.276A>C variant is a missense variant predicted to cause substitution of glutamine to histidine at amino acid position 92 (p.(Gln92His)). The highest population minor allele frequency in gnomAD v2.1.1 (controls) is 0.001589 in the East Asian population (Korean) (BS1 met but not PM2 or BA1). Computational predictor REVEL score is 0.57, which is in between the PH-VCEP specified threshold of ≤0.25 and ≥0.75, so neither PP3 nor BP4 are met. This variant is located in the extracellular domain, critical for ligand binding (PM1 met), but does not affect a known critical or non-critical amino acid (no up- or downward adjustment for PM1). BS2 was not met due to absence of homozygous individuals (gnomAD v.2.1.1 controls). PS4 was not applied as PM2 was not met. PP1, PS2, PM6 were not met due to the absence of co-segregation data. PS3 and BS3 were not met due to the lack of experimental evidence. Although other variants in the same amino acid been reported, for pulmonary arterial hypertension, the variants were not deemed pathogenic or likely pathogenic by the PH-VCEP (PS1, PM5 not met). 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, PM1 (VCEP specification version 1.1.0, 1/18/2024).
