Recommendations for diagnostic genetic testing for familial interstitial pneumonia (FIP)–associated genetic variants. *Age 18 is included because at this age patients will have reached majority and can provide personal consent for genetic testing and/or sharing of protected health information; however, consideration should be given to testing for surfactant mutations in patients with FIP with a family history of disease onset before age 30. IIP = idiopathic interstitial pneumonia; PBMC = peripheral blood mononuclear cell.
