BMPR1A
A gene located on chromosome 10 in band 10q22.3 that encodes bone morphogenic protein receptor 1A, a kinase receptor that is involved in bone morphogenetic protein (BMP) signaling.
Mutations in BMPR1A account for 25% to 40% of cases of juvenile polyposis, an autosomal dominant gastrointestinal polyposis syndrome in which patients are at risk for developing gastrointestinal cancers
