In 2006, Mathijssen et al. described an adult male intellectually disabled patient who had calcified pinnae and a neoplasm of the palate. The patient also had extensive hearing loss, little to no body hair, distorted facial features, and joint contractures. The patient also developed testicular cancer, but it is unknown whether or not it is related to the syndrome. The patient experienced cryptorchidism, a birth defect where one of the testes is not present at birth, that may have played a part in the formation of the tumor.
