Hb SS disease

Sickle cell disease (SCD) is characterized by intermittent vaso-occlusive events and chronic hemolytic anemia. Vaso-occlusive events result in tissue ischemia leading to acute and chronic pain as well as organ damage that can affect any organ in the body, including the bones, lungs, liver, kidneys, brain, eyes, and joints. Dactylitis (pain and/or swelling of the hands or feet) in infants and young children is often the earliest manifestation of sickle cell disease. In children the spleen can become engorged with blood cells in a “splenic sequestration.” The spleen is particularly subject to infarction and the majority of individuals with SCD are functionally asplenic in early childhood, increasing their risk for certain types of bacterial infections. Chronic hemolysis can result in varying degrees of anemia, jaundice, cholelithiasis, and delayed growth and sexual maturation. Individuals with the highest rates of hemolysis are predisposed to pulmonary artery hypertension, priapism, and leg ulcers but may be relatively protected from vaso-occlusive pain. [from GeneReviews]

HEMOGLOBIN S

Presence of an abnormal type of hemoglobin characterized by the subsitution of a glutamic acid residue at position 7 following the initial methionine residue by a valine (the mutation causative of sickle cell disease). The mutation promotes the polymerization of the HbS under conditions of low oxygen concentration. HbS can be identified by multiple methodologies including hemoglobin electrophoresis and high-performance liquid chromatography. [from HPO]

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. Anemia has three main causes: blood loss, lack of red blood cell production, and high rates of red blood cell destruction. Conditions that may lead to anemia include. -Heavy periods. -Pregnancy. -Ulcers. -Colon polyps or colon cancer. -Inherited disorders. -A diet that does not have enough iron, folic acid or vitamin B12. -Blood disorders such as sickle cell anemia and thalassemia, or cancer. -Aplastic anemia, a condition that can be inherited or acquired. -G6PD deficiency, a metabolic disorder. Anemia can make you feel tired, cold, dizzy, and irritable. You may be short of breath or have a headache. Your doctor will diagnose anemia with a physical exam and blood tests. Treatment depends on the kind of anemia you have. NIH: National Heart, Lung, and Blood Institute.  [from MedlinePlus]

Schnyder crystalline corneal dystrophy

Schnyder corneal dystrophy (SCCD), also known as Schnyder crystalline corneal dystrophy, is an autosomal dominant eye disease characterized by abnormal deposition of cholesterol and phospholipids in the cornea. The consequent corneal opacification is progressive and bilateral, resulting in glare and loss of vision that is postulated to be caused by light scattering. Patients demonstrate a characteristic pattern of corneal opacification dependent on age, and only half have crystalline corneal cholesterol deposits. Patients with noncrystalline disease have a more subtle presentation with only corneal haze, which may be difficult to diagnose (summary by Nickerson et al., 2013). [from OMIM]

Renal carnitine transport defect

Systemic primary carnitine deficiency (CDSP) is a disorder of the carnitine cycle that results in defective fatty acid oxidation. It encompasses a broad clinical spectrum including: Metabolic decompensation in infancy typically presenting between age three months and two years with episodes of hypoketotic hypoglycemia, poor feeding, irritability, lethargy, hepatomegaly, elevated liver transaminases, and hyperammonemia triggered by fasting or common illnesses such as upper respiratory tract infection or gastroenteritis; Childhood myopathy involving heart and skeletal muscle with onset between age two and four years; Pregnancy-related decreased stamina or exacerbation of cardiac arrhythmia; Fatigability in adulthood; Absence of symptoms. The latter two categories often include mothers diagnosed with CDSP after newborn screening has identified low carnitine levels in their infants. [from GeneReviews]

Congenital, Hereditary, and Neonatal Diseases and Abnormalities

Diseases existing at birth and often before birth, or that develop during the first month of life (INFANT, NEWBORN, DISEASES), regardless of causation. Of these diseases, those characterized by structural deformities are termed CONGENITAL ABNORMALITIES. [from MeSH]

Hemic and Lymphatic Diseases

Hematologic diseases and diseases of the lymphatic system collectively. Hemic diseases include disorders involving the formed elements (e.g., ERYTHROCYTE AGGREGATION, INTRAVASCULAR) and chemical components (e.g., BLOOD PROTEIN DISORDERS); lymphatic diseases include disorders relating to lymph, lymph nodes, and lymphocytes. [from MeSH]

Hematologic disease

Your blood is living tissue made up of liquid and solids. The liquid part, called plasma, is made of water, salts and protein. Over half of your blood is plasma. The solid part of your blood contains red blood cells, white blood cells and platelets. Blood disorders affect one or more parts of the blood and prevent your blood from doing its job. They can be acute or chronic. Many blood disorders are inherited. Other causes include other diseases, side effects of medicines, and a lack of certain nutrients in your diet. Types of blood disorders include. -Platelet disorders, excessive clotting, and bleeding problems, which affect how your blood clots. -Anemia, which happens when your blood does not carry enough oxygen to the rest of your body. -Cancers of the blood, such as leukemia and myeloma. -Eosinophilic disorders, which are problems with one type of white blood cell.  [from MedlinePlus]
