BMPR1A (P36894) variants and mutations

BMPR1A (also known as P36894) is a human protein-coding gene encoding a bone morphogenetic protein receptor type-1A protein. It transduces BMP signals that regulate epithelial growth, differentiation, and tissue patterning through SMAD proteins and other pathways. Germline loss-of-function variants cause juvenile polyposis syndrome and can substantially increase gastrointestinal cancer risk. This analysis covers 1,427 BMPR1A variants and mutations. Of these, 74% have computational variant effect predictions. Disease context includes juvenile polyposis syndrome, hereditary mixed polyposis syndrome, and generalized juvenile polyposis/juvenile polyposis coli. Example BMPR1A variants include M1?, M1I, and M1L.
