Genes
Name	Description
Bone Diseases	Your bones help you move, give you shape and support your body. They are living tissues that rebuild constantly throughout your life. There are many kinds of bone problems: Osteoporosis makes your bones weak and more likely to break. Osteogenesis imperfecta makes your bones brittle. Bones can also develop cancer. Other bone diseases are caused by poor nutrition, genetic factors or problems with the rate of bone growth or rebuilding. MedlinePlus health topic
Lung Neoplasms	Lung neoplasm or lung cancer is a disease of uncontrolled cell growth in tissues of the lung. This growth may lead to metastasis, invasion of adjacent tissue and infiltration beyond the lungs. The vast majority of primary lung cancers are carcinomas of the lung, derived from epithelial cells. Lung cancer, the most common cause of cancer-related death in men and the second most common in women, is responsible for 1.3 million deaths worldwide annually. In the UK, it is the most common site of fatal cancer in both men and women. The most common symptoms are shortness of breath, coughing (including coughing up blood), and weight loss. Wikipedia
Infection	Infection is the general term for invasion and growth of microorganisms in bodily tissues. GHR - Glossary
Breast Diseases	Diseases of the breast. MedlinePlus health topic
Cerebrovascular Disorders	Cerebrovascular disease is a group of brain dysfunctions related to disease of blood vessels supplying the brain. Hypertension is the most important cause that damages the blood vessel lining endothelium exposing the underlying collagen where platelets aggregate to initiate a repairing process which is not always complete and perfect. Sustained hypertension permanently changes the architecture of the blood vessels making them narrow, stiff, deformed and uneven which are more vulnerable to fluctuations of blood pressure. A fall in blood pressure during sleep can lead to marked reduction in blood flow in the narrowed blood vessels causing ischemic stroke in the morning whereas a sudden rise in blood pressure can cause tearing of the blood vessels causing intracranial hemorrhage during excitation at daytime. Primarily people who are elderly, diabetic, smoker, or have ischemic heart disease, have cerebrovascular disease. All diseases related to artery dysfunction can be classified under a disease as known as Macrovascular disease. This is a simplistic study by which arteries are blocked by fatty deposits or by a blood clot. The results of cerebrovascular disease can include a stroke, or even sometimes a hemorrhagic stroke. Ischemia or other blood vessel dysfunctions can affect one during a cerebrovascular accident. Wikipedia
Leukemia	Cancer of blood-forming tissue. GHR - Glossary
Colonic Diseases	Your colon, also known as the large intestine, is part of your digestive system. It's a long, hollow tube at the end of your digestive tract where your body makes and stores stool. Many disorders affect the colon's ability to work properly. MedlinePlus health topic
Neuroendocrine Tumors	Neuroendocrine tumors, or more properly gastro-entero-pancreatic or gastroenteropancreatic neuroendocrine tumors (GEP-NETs), are cancers of the interface between the endocrine (hormonal) system and the nervous system. Wikipedia
Hemorrhage	Bleeding or escape of blood from a vessel. GHR - Glossary
Anemia	If you have anemia, your blood does not carry enough oxygen to the rest of your body. The most common cause of anemia is not having enough iron. Your body needs iron to make hemoglobin. Hemoglobin is an iron-rich protein that gives the red color to blood. It carries oxygen from the lungs to the rest of the body. MedlinePlus health topic
Central Nervous System Neoplasms	A brain tumor is any intracranial tumor created by abnormal and uncontrolled cell division, normally either in the brain itself (neurons, glial cells (astrocytes, oligodendrocytes, ependymal cells), lymphatic tissue, blood vessels), in the cranial nerves (myelin-producing Schwann cells), in the brain envelopes (meninges), skull, pituitary and pineal gland, or spread from cancers primarily located in other organs (metastatic tumors). Primary (true) brain tumors are commonly located in the posterior cranial fossa in children and in the anterior two-thirds of the cerebral hemispheres in adults, although they can affect any part of the brain. In the United States in the year 2005, it was estimated that there were 43,800 new cases of brain tumors (Central Brain Tumor Registry of the United States, Primary Brain Tumors in the United States, Statistical Report, 2005 - 2006),[1] which accounted for 1.4 percent of all cancers, 2.4 percent of all cancer deaths,[2] and 20–25 percent of pediatric cancers.[2][3] Ultimately, it is estimated that there are 13,000 deaths/year as a result of brain tumors.[1] Wikipedia
Pain	Pain is a feeling triggered in the nervous system. Pain may be sharp or dull. It may come and go, or it may be constant. You may feel pain in one area of your body, such as your back, abdomen or chest, or you may feel pain all over, such as when your muscles ache from the flu. MedlinePlus health topic
Breast Neoplasms	Breast cancer is a cancer that starts in the cells of the breast. Worldwide, breast cancer is the second most common type of cancer after lung cancer (10.4% of all cancer incidence, both sexes counted) and the fifth most common cause of cancer death. Worldwide, breast cancer is by far the most common cancer amongst women, with an incidence rate more than twice that of colorectal cancer and cervical cancer and about three times that of lung cancer. However breast cancer mortality worldwide is just 25% greater than that of lung cancer in women. Wikipedia
Hypersensitivity, Immediate	Hypersensitivity reactions which occur within minutes of exposure to challenging antigen due to the release of histamine which follows the antigen-antibody reaction and causes smooth muscle contraction and increased vascular permeability. Wikipedia
Heart Diseases	Heart disease is the number one killer in the U.S. It is also a major cause of disability. The most common cause of heart disease is narrowing or blockage of the coronary arteries, the blood vessels that supply blood to the heart itself. This is called coronary artery disease and happens slowly over time. It's the major reason people have heart attacks. MedlinePlus health topic
Skin Diseases	Conditions that irritate, clog or inflame your skin can cause symptoms such as redness, swelling, burning and itching. Allergies, irritants, your genetic makeup and certain diseases and immune system problems can cause dermatitis, hives and other skin conditions. Many skin problems, such as acne, also affect your appearance. MedlinePlus health topic
Respiratory Hypersensitivity	A form of hypersensitivity affecting the respiratory tract. It includes ASTHMA and RHINITIS, ALLERGIC, SEASONAL. MeSH Definition
Gram-Negative Bacterial Infections	Gram-negative bacteria are those bacteria that do not retain crystal violet dye in the Gram staining protocol.[1] Gram-positive bacteria will retain the crystal violet dye when washed in a decolorizing solution. In a Gram stain test, a counterstain (commonly safranin) is added after the crystal violet, coloring all Gram-negative bacteria a red or pink color. The test itself is useful in classifying two distinct types of bacteria based on structural differences in their cell walls. Wikipedia
Urogenital Neoplasms	A urogenital neoplasm is a tumor of the urogenital system. Wikipedia
Brain Neoplasms	A brain tumor is any intracranial tumor created by abnormal and uncontrolled cell division, normally either in the brain itself (neurons, glial cells (astrocytes, oligodendrocytes, ependymal cells), lymphatic tissue, blood vessels), in the cranial nerves (myelin-producing Schwann cells), in the brain envelopes (meninges), skull, pituitary and pineal gland, or spread from cancers primarily located in other organs (metastatic tumors).

Poisoning	A poison is any substance that is harmful to your body. You might swallow it, inhale it, inject it or absorb it through your skin. MedlinePlus health topic
Hepatitis	Your liver helps your body digest food, store energy and remove poisons. Hepatitis is a swelling of the liver that makes it stop working well. It can lead to scarring, called cirrhosis, or to cancer. MedlinePlus health topic
Gastroenteritis	Have you ever had the stomach flu? What you probably had was gastroenteritis - not a type of flu at all. Gastroenteritis is an inflammation of the lining of the intestines caused by a virus, bacteria or parasites. Viral gastroenteritis is the second most common illness in the U.S. It spreads through contaminated food or water, and contact with an infected person. The best prevention is frequent hand washing. MedlinePlus health topic
Protozoan Infections	A condition which is characterized by an infection caused by protozoans. Protozoa are microorganisms that differ from bacteria in that they are larger and possess a nucleus surrounded by a membrane. Several species of protozoa can be transmitted through water and cause disease in humans, including Giardia, Cryptosporidium, Cyclospora, Entamoeba and Isospora. Wikipedia
Esophageal Diseases	The esophagus or oesophagus (see American and British English spelling differences), sometimes known as the gullet, is an organ in vertebrates which consists of a muscular tube through which food passes from the pharynx to the stomach. In humans the oesophagus is continuous with the laryngeal part of the pharynx at the level of the C6 vertebra. It is usually 25-30 cm long which connects the mouth to the stomach. It is divided into cervical, thoracic, and abdominal parts. Wikipedia
Neoplasms, Connective and Soft Tissue	Neoplasms developing from some structure of the connective and subcutaneous tissue. The concept does not refer to neoplasms located in connective or soft tissue. Wikipedia
Pathological Conditions, Anatomical	An abnormal structural condition of the human body, usually macroscopic, that is common to a variety of different diseases. MeSH Definition
Tooth Diseases	Teeth (singular, tooth) are small white structures found in the jaws (or mouths) of many vertebrates that are used to tear, scrape, milk and chew food. Some animals, particularly carnivores, also use teeth for hunting or defense. The roots of teeth are covered by gums. Wikipedia
Asthma	Asthma is a chronic disease that affects your airways. Your airways are tubes that carry air in and out of your lungs. If you have asthma, the inside walls of your airways become sore and swollen. That makes them very sensitive, and they may react strongly to things that you are allergic to or find irritating. When your airways react, they get narrower and your lungs get less air. This can cause wheezing, coughing, chest tightness and trouble breathing, especially early in the morning or at night. MedlinePlus health topic
Pregnancy Complications	Complications of pregnancy are the symptoms and problems that are associated with pregnancy. There are both routine problems and serious, even potentially fatal problems. The routine problems are normal complications, and pose no significant danger to either the woman or the fetus. Serious problems can cause both maternal death and fetal death if untreated. Wikipedia
