Is BMPR2 p.Ala384Val (c.1151C>T) pathogenic?

BMPR2 p.Ala384Val (c.1151C>T) is classified Likely pathogenic in BMPR2 (ClinVar, Expert panel, 2 submitters; last evaluated 2026-04-09). AlphaMissense: likely pathogenic (0.9915); Absent from gnomAD v4.1; Associated with pulmonary arterial hypertension.

What condition is associated with BMPR2 p.Ala384Val (c.1151C>T)?

BMPR2 p.Ala384Val (c.1151C>T) is associated with pulmonary arterial hypertension, pulmonary hypertension, primary, 1 (ClinVar).

How common is BMPR2 p.Ala384Val (c.1151C>T) in the general population?

BMPR2 p.Ala384Val (c.1151C>T) is absent from gnomAD v4.1 (gnomAD).

What do computational predictors say about BMPR2 p.Ala384Val (c.1151C>T)?

AlphaMissense predicts likely pathogenic (score 0.9915) — an in-silico prediction, not a clinical call.

BMPR2 p.Ala384Val

Q: How is Idiopathic/heritable pulmonary arterial hypertension inherited?

Typically Autosomal dominant, Autosomal recessive (Orphanet). A genetic counselor can assess individual risk for a family.

Likely Pathogenic for pulmonary arterial hypertension. Applied ACMG criteria (verbatim):

PM2_Supporting PS4_Supporting PM1_moderate PP2 PP3_supporting

Curation rationale (ClinGen, verbatim)

The c.1151C>T (p.Ala384Val) variant is a missense variant located in exon 9 of the BMPR2 gene, predicted to cause substitution of alanine to valine encoding the functionally relevant catalytic kinase domain but without functional evidence indicating critical or non-critical (PM1_moderate). This variant is absent from gnomAD v2.1.1 (controls) and v4.1 (PM2_supporting). BMPR2 has a low rate of benign missense variants and missense variants are a common mechanism of disease (PP2). The REVEL prediction algorithm score is 0.917 and AlphaMissense is 0.9915 indicating pathogenicity (PP3_met). The variant has been reported in one Japanese individual (PMID: 23675998) and one Chinese individual (PMID: 30578397, PMID: 32634488) with idiopathic PAH (PS4_supporting). PS2 was not assessed due to lack of paternity data. Functional studies have not been conducted for this variant (PS3 not assessed). In summary, this variant meets the criteria to be classified as a likely pathogenic for pulmonary arterial hypertension based on the ACMG/AMP criteria applied, as specified by the ClinGen Pulmonary Hypertension VCEP: PM1_moderate, PM2_supporting, PP2, PP3_supporting (VCEP specification version 2.0, 1/30/2026).
