Disease Overview

Peutz-Jeghers syndrome (PJS) is an inherited condition that is associated with an increased risk of growths along the lining of the gastrointestinal tract (called hamartomatous polyps) and certain types of cancer. Most affected people also have characteristic dark blue to dark brown macules around the mouth, eyes, and nostrils; near the anus (perianal); and on the inside of the cheeks (buccal mucosa). PJS is caused by changes (mutations) in the STK11 gene and is inherited in an autosomal dominant manner.[8500][8501] Management typically includes high-risk screening for associated polyps and cancers.[8502]
