Description

The SMAD9 c.296C>T variant is predicted to result in the amino acid substitution p.Pro99Leu. This variant was reported in a large study of patients with idiopathy pulmonary arterial hypertension. A different missense change altering the same residue was reported in a patient from the same study (p.Pro99Ala; Gräf et al. 2018. PubMed ID: 29650961). The p.Pro99Leu variant has not been reported in a large population database (http://gnomad.broadinstitute.org), indicating this variant is rare. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence.
