Neurofibromatosis type 2 is a disorder characterized by the growth of noncancerous tumors in the nervous system.

Cystic Fibrosis: Introduction. Cystic fibrosis is a chronic, progressive and debilitating disease that affects the lungs, intestines, liver, and pancreas. Cystic fibrosis is caused by a genetic defect that triggers the mucous producing glands of the body to make excessive amounts of abnormally thick and sticky mucus. Cystic fibrosis results in the clogging of the tubes, ducts and air passages of the body with mucus. This leads to serious problems with digestion and breathing.
