Is BMPR2 p.Val392Ala (c.1175T>C) pathogenic?

BMPR2 p.Val392Ala (c.1175T>C) is classified Uncertain significance in BMPR2 (ClinVar, Expert panel, 2 submitters; last evaluated 2024-11-06). AlphaMissense: likely pathogenic (0.9795); Absent from gnomAD v4.1; Associated with pulmonary arterial hypertension.

What condition is associated with BMPR2 p.Val392Ala (c.1175T>C)?

BMPR2 p.Val392Ala (c.1175T>C) is associated with pulmonary arterial hypertension, pulmonary hypertension, primary, 1 (ClinVar).

How common is BMPR2 p.Val392Ala (c.1175T>C) in the general population?

BMPR2 p.Val392Ala (c.1175T>C) is absent from gnomAD v4.1 (gnomAD).

What do computational predictors say about BMPR2 p.Val392Ala (c.1175T>C)?

AlphaMissense predicts likely pathogenic (score 0.9795) — an in-silico prediction, not a clinical call.

BMPR2 p.Val392Ala

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.

Uncertain Significance for pulmonary arterial hypertension. Applied ACMG criteria (verbatim):

PM2_Supporting PM1_met PP3_met

Curation rationale (ClinGen, verbatim)

The NM_001204.7(BMPR2) c.1175T>C (p.Val392Ala) variant is located in exon 9 of the BMPR2 gene and is absent from gnomAD v2.1.1 (controls) and v4.1.0 (PM2_supporting). The variant is located in the functionally relevant catalytic kinase domain (PM1_met) but is not a critical or non-critical residue. The variant has been reported in only one individual with IPAH (PMID: 21737554 and 20002458) (PS4 not met). The REVEL score for the variant is 0.954, which is greater than the PH VCEP threshold of >= 0.75, and the AlphaMissense score is 0.9795, indicating pathogenicity (PP3_met). No segregation or parental data were found (PP1 and PS2 not evaluated). No other amino acid change at the same position has been reported for PAH (PS1 and PM5 not evaluated). No functional evidence was found (PS3 not evaluated). In summary, this variant meets the criteria to be classified as a variant of uncertain significance for pulmonary arterial hypertension based on the ACMG/AMP criteria applied, as specified by the ClinGen Pulmonary Hypertension VCEP: PM2_supporting, PM1, PP3 (VCEP specification version 1.1.0, 1/18/2024).

ClinVar classifies this uncertain; the computational predictors unanimously lean damaging — a triage signal, not a reclassification

AlphaMissense carries the ACMG weight for missense; REVEL and SaProt are independent agreement signals.
