A Cowden-like syndrome has been found to be caused by mutation in the BMPR1A gene; CLINICAL FEATURES ; Multiple hamartomatous lesions, especially of the skin, mucous membranes, breast and thyroid, are encountered; Verrucous skin lesions of the face and limbs, cobblestone-like papules of the gingiva and buccal mucosa, and multiple facial trichilemmomas are leading findings; Hamartomatous polyps of the colon and other intestines occur also; acute myelogenous leukemia reported ;Breast cancer as well; anticipation occurs with earlier symptoms each generation--------------[OMIM 2004]--------------
