We formed a ClinGen variant curation expert panel to devise guidelines for the clinical interpretation of <jats:italic>BMPR2<\/jats:italic> variants identified in PAH patients. The general ACMG\/AMP variant classification criteria were refined for PAH and adapted to <jats:italic>BMPR2<\/jats:italic> following ClinGen procedures. Subsequently, these specifications were tested independently by three members of the curation expert panel on 28 representative <jats:italic>BMPR2<\/jats:italic> variants selected from ClinVar and then presented and discussed in the plenum. Application of the final <jats:italic>BMPR2<\/jats:italic> variant specifications resolved six of nine variants (66%) where multiple ClinVar classifications included a variant of uncertain significance, with all six being reclassified as Benign or Likely Benign. Four splice site variants underwent clinically consequential reclassification based on the presence or absence of supporting mRNA splicing data. These variant specifications provide an international framework and a valuable tool for <jats:italic>BMPR2<\/jats:italic> variant classification that can be applied to increase confidence and consistency in <jats:italic>BMPR2<\/jats:italic> interpretation for diagnostic laboratories, clinical providers, and patients.<\/jats:p>","DOI":"10.1155\/humu\/2475635","type":"journal-article","created":{"date-parts":[[2025,7,7]],"date-time":"2025-07-07T07:31:03Z","timestamp":1751873463000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Adaptation
