Juvenile polyposis and other intestinal polyposis syndromes with microdeletions of chromosome 10q22–23

Abstract excerpt

Juvenile polyposis (JP) is an autosomal dominant hamartomatous polyposis syndrome that carries a significant risk for the development of colorectal cancer. Microdeletions of one of the two predisposing genes to JP, BMPR1A, have been associated with a severe form of JP called juvenile polyposis of infancy. Many of these deletions have also been found to contiguously include PTEN, which is the gene responsible for...
