Methylation profiling by array of a solitary Peutz-Jeghers colon polyp in a healthy individual

ABSTRACT: Colon polyps represent precursor lesions of colon cancers and their malignant potential varies according to histological subtype. A rare subtype of colon polyps is the Peutz-Jeghers (PJ) polyp. PJ polyps mostly occur in the context of Peutz-Jeghers Syndrome which is characterized by the development of multiple polyps in the intestinal tract and hyperpigmentation of oral mucosa and lips. Peutz-Jeghers Syndrome is an autosomal dominant disorder caused by germline mutations of the Serine Threonin Kinase STK11 (LKB1). PJ polyps very rarely occur outside of Peutz-Jeghers Syndrome and are then referred to as solitary PJ polyps. Contrary to Peutz-Jeghers Syndrome, the genetic basis and the malignant potential of solitary PJ polyps is currently unknown. To date, only one study described a sporadic
