A rare recurring gain-of-function variant in BMPR2 causes neurodevelopmental phenotypes in humans and flies.
Bone morphogenetic protein receptor type 2 (BMPR2) encodes an evolutionarily conserved serine/threonine kinase that phosphorylates type-1 BMP receptors to mediate intercellular communication upon ligand binding. Loss-of-function variants in BMPR2 are known to cause pulmonary arterial hypertension and other cardiovascul...
