What is (are) Thalassemia ? 

Thalassemia is an inherited blood disorder that reduces the production of functional hemoglobin (the protein in red blood cells that carries oxygen). This causes a shortage of red blood cells and low levels of oxygen in the bloodstream, leading to a variety of health problems. There are two main types of thalassemia, alpha thalassemia and beta thalassemia. Signs and symptoms vary but may include mild to severe anemia, paleness, fatigue, yellow discoloration of skin (jaundice), and bone problems. Beta thalassemia is caused by changes (mutations) in the HBB gene while alpha thalassemia is caused by mutations in the HBA1 and/or HBA2 genes. Both are inherited in an autosomal recessive manner. Treatment depends on the type and severity of the condition but may include blood transfusions and/or folic acid supplements.
What are the symptoms of Thalassemia ? 

What are the signs and symptoms of Thalassemia? The signs and symptoms vary depending on the severity of the thalassemia. For example, people affected by milder forms of thalassemia can develop mild anemia or may have no signs or symptoms of the condition at all. Intermediate forms of thalassemia can cause mild to moderate anemia and may be associated with other health problems such as slowed growth, delayed puberty, bone problems and/or an enlarged spleen. In addition to the signs and symptoms seen in intermediate thalassemia, people with severe forms of thalassemia may also experience severe anemia, poor appetite, paleness, dark urine, yellow discoloration of skin (jaundice), and enlarged liver or heart.

If the information is available, the table below includes how often the symptom is seen in people with this condition. You can use the MedlinePlus Medical Dictionary to look up the definitions for these medical terms. Signs and Symptoms Approximate number of patients (when available) Abnormality of the heme biosynthetic pathway 90% Abnormality of immune system physiology 7.5% Biliary tract abnormality 7.5% Cognitive impairment 7.5% Hemolytic anemia 7.5% Hydrops fetalis 7.5% Hypersplenism 7.5% Myelodysplasia 7.5% Splenomegaly 7.5% Hypochromic microcytic anemia - Reduced alpha/beta synthesis ratio - The Human Phenotype Ontology (HPO) has collected information on how often a sign or symptom occurs in a condition. Much of this information comes from Orphanet, a European rare disease database. The frequency of a sign or symptom is usually listed as a rough estimate of the percentage of patients who have that feature. The frequency may also be listed as a fraction. The first number of the fraction is how many people had the symptom, and the second number is the total number of people who were examined in one study. For example, a frequency of 25/25 means that in a study of 25 people all patients were found to have that symptom. Because these frequencies are based on a specific study, the fractions may be different if another group of patients are examined. Sometimes, no information on frequency is available. In these cases, the sign or symptom may be rare or common.
What causes Thalassemia ? 

What causes thalassemia? There are two main types of thalassemia, alpha thalassemia and beta thalassemia, which each affect a different part of hemoglobin (the protein in red blood cells that carries oxygen). Hemoglobin is made up of two different components (subunits): beta globin and alpha globin. The HBB gene provides instructions for making beta globin, while the HBA1 and HBA2 genes provide instructions for making alpha globin. Each person has two copies of each of these genes, one inherited from the mother and one from the father. Changes (mutations) in the HBB gene lead to reduced levels of beta globin and cause beta thalassemia. Loss (deletion) of some or all of the HBA1 and/or HBA2 genes results in a shortage of alpha globin, leading to alpha thalassemia.
Is Thalassemia inherited ? 

How is thalassemia inherited? In general, thalassemia is inherited in an autosomal recessive manner; however, the inheritance can be quite complex as multiple genes can influence the production of hemoglobin. Most people affected by beta thalassemia have mutations in both copies of the HBB gene in each cell. The parents of an affected person usually each carry one mutated copy of the gene and are referred to as carriers. Carriers typically do not show signs or symptoms of the condition; although some carriers of beta thalassemia develop mild anemia. When two carriers of an autosomal recessive condition have children, each child has a 25% (1 in 4) risk to have the condition, a 50% (1 in 2) risk to be a carrier like each of the parents, and a 25% chance to not have the condition and not be a carrier. The inheritance of alpha thalassemia is complicated by the fact that mutations in two different genes (HBA1 and HBA2) are associated with the condition. People have two copies of the HBA1 gene and two copies of the HBA2 gene in each cell. For each gene, one copy is inherited from the mother and one is inherited from the father. If each parent is missing at least one gene copy, their children are at risk for having alpha thalassemia. However, the exact risk and the severity of each child's condition depends on how many gene copies are lost (deleted) and which combination of the HBA1 and HBA2 genes are affected.
How to diagnose Thalassemia ? 

Is genetic testing available for thalassemia? Yes, genetic testing is available for HBB, HBA1 and HBA2, the genes known to cause thalassemia. Carrier testing for at-risk relatives and prenatal testing are possible if the disease-causing mutations in the family are known. The Genetic Testing Registry (GTR) is a centralized online resource for information about genetic tests. It has additional information on genetic testing for alpha thalassemia and beta thalassemia. The intended audience for the GTR is health care providers and researchers. Patients and consumers with specific questions about a genetic test should contact a health care provider or a genetics professional.
What are the treatments for Thalassemia ? 

How might thalassemia be treated? The best treatment options depend on the severity of thalassemia. People affected by a mild form often need little to no treatment, while people with intermediate to severe thalassemias may require frequent blood transfusions, iron chelation therapy (treatments to remove excess iron from the body), and/or folic acid supplementation.

What is (are) Clear cell renal cell carcinoma ? 

Clear cell renal cell carcinoma is a cancer of the kidney.  The name "clear cell" refers to the appearance of the cancer cells when viewed with a microscope.[5258]  Clear cell renal cell carcinoma occurs when cells in the kidney quickly increase in number, creating a lump (mass).  Though the exact cause of clear cell renal cell carcinoma is unknown, smoking, the excessive use of certain medications, and several genetic predisposition conditions (such as von Hippel Lindau syndrome) may contribute to the development of this type of cancer.  Treatment often begins with surgery to remove as much of the cancer as possible, and may be followed by radiation therapy, chemotherapy, biological therapy, or targeted therapy.
What are the treatments for Clear cell renal cell carcinoma ? 

What treatments for metastatic clear cell renal cell carcinoma are available in North America? There are several treatments for metastatic clear cell renal cell carcinoma available in North America.  IL-2 and sunitinib - as well as the medications temsirolimus, bevacizumab with interferon therapy, pazopanib, and sorafenib - are approved by the Food and Drug Administration for the treatment of metastatic clear cell renal cell carcinoma.  Because a cure for this disease has yet to be discovered, the National Cancer Institute suggests that individuals with metastatic clear cell renal cell carcinoma consider participation in a research study. IL-2 is offered as a treatment for this disease in some individuals because it has been shown to cause a complete disappearance of signs of this disease (remission) in 5% of treated patients.  As IL-2 may cause toxic side effects, it is most appropriate for patients who are in excellent health.  Sunitinib is offered because it has been shown to stabilize metastatic clear cell renal cell carcinoma by stopping the disease from getting worse.  Individuals treated with sunitinib showed no change in their disease for an average of 11 months.
What is (are) Cat scratch disease ? 

Cat scratch disease is an infectious illness caused by the bacteria bartonella. It is believed to be transmitted by cat scratches, bites, or exposure to cat saliva. This self-limiting infectious disease is characterized by a bump or blister at the site of the bite or scratch and swelling and pain in the lymph nodes. Other features may include fatigue, headache, achiness, and fever. Although cat-scratch disease usually subsides without treatment, antibiotic and/or antimicrobial therapy may help speed recovery.
What are the symptoms of Cat scratch disease ? 

What are the symptoms of cat scratch disease? Most people with cat scratch disease have been bitten or scratched by a cat and developed a mild infection at the point of injury. Lymph nodes, especially those around the head, neck, and upper limbs, become swollen. Additionally, a person with cat scratch disease may experience fever, headache, fatigue, achiness and discomfort (malaise), sore throat, enlarged spleen, and/or loss of appetite.

What is (are) Congenital chloride diarrhea ? 

Congenital chloride diarrhea is a condition characterized by large, watery stools containing an excess of chloride. Individuals have intrauterine (pre-birth) and lifelong diarrhea; infants with the condition are often premature. The excessive diarrhea causes electrolyte and water deficits, which in turn cause volume depletion, hyperreninemia (elevated levels of renin in the blood), hyperaldosteronism, renal potassium wasting, and sometimes nephropathy. Mutations in the SLC26A3 gene have been found to cause the condition. It is inherited in an autosomal recessive manner. Treatment generally focuses on the individual symptoms of the condition and typically includes taking oral supplements of sodium and potassium chloride.

What are the treatments for Congenital chloride diarrhea ? 

How might congenital chloride diarrhea be treated? There is no cure for the underlying condition, so treatment mainly focuses on the symptoms. Studies have shown that early diagnosis and aggressive salt replacement therapy (replacing sodium and chloride, the 2 things that make up salt) are associated with normal growth and development, in addition to reduced mortality rates. In individuals with this condition, the goal is for the oral intake of chloride, sodium, and potassium to be greater than the amount lost through the feces (i.e., there must be a positive gastrointestinal balance) so that losses in sweat can be replaced. Replacement therapy with NaCl (sodium chloride) and KCl (potassium chloride) has been shown to be effective in children. One study showed that a medication called omeprazole, a proton-pump inhibitor, reduces electrolyte losses in individuals and thus promotes a positive gastrointestinal balance. However, this treatment does not reduce the need for careful monitoring of dietary intake, electrolyte concentrations, and urinary chloride loss. Another study discussed how butyrate could be effective in treating the condition, and that it is easily administered, useful in preventing severe dehydration episodes, and may be a promising approach for a long-term treatment.

What is (are) Tetrahydrobiopterin deficiency ? 

Tetrahydrobiopterin (BH4) deficiency is a neurological condition caused by an inborn error of metabolism. BH4 is a substance in the body that enhances the action of other enzymes. Deficiency of BH4 leads to abnormally high blood levels of the amino acid phenylalanine, and low levels of certain neurotransmitters. Signs and symptoms can range from very mild to severe. Affected newborns appear normal at birth, but may begin to experience neurological symptoms such as abnormal muscle tone; poor sucking and coordination; seizures; and delayed motor development. Without early, appropriate treatment, the condition can cause permanent intellectual disability and even death. BH4 deficiency is caused by mutations in any one of several genes including the GCH1, PCBD1, PTS, and QDPR genes. It is inherited in an autosomal recessive manner.Treatment depends on the genetic cause and severity, and may include a low phenylalanine diet; oral BH4 supplementation; and neurotransmitter replacement.
What are the symptoms of Tetrahydrobiopterin deficiency ? 

What are the signs and symptoms of Tetrahydrobiopterin deficiency? Infants with tetrahydrobiopterin (BH4) deficiency typically appear normal and healthy at birth. Neurological signs and symptoms usually become apparent over time, and can range from mild to severe. These may include abnormal muscle tone; poor sucking and coordination; seizures; and delayed motor development. Other manifestations may include decreased spontaneous movements and difficulty swallowing. Without early and appropriate treatment, signs and symptoms progress and affected individuals may experience irreversible intellectual disability, behavioral problems, an inability to control body temperature, and even death in severe cases.
