What Are The Causes Of Sickle Cell Disease
Inheritance: The sickle cell gene is a mutation in the way the hemoglobin molecule is formed.It takes a pair of sickle genes to cause the change.A single normal gene can cancel the abnormal gene effect. Parents with a single sickle cell gene will be asymptomatic. When a baby gets a sickle gene from both parents, the abnormal genes are expressed as SS disease. ...Read more
Well tolerated drug.: Hydrea (hydroxyurea) is a chemotherapy like drug that can help prevent painful crises in patients with sickle cell disease. It is well tolerated for the most part. There can be fatigue, mouth sores and loose stools. It will routinely lower the white blood cell count and platelets, but not to dangerous levels. Hemoglobin may actually improve. There is ? Of leukemia risk in other diseases, but not in scd. ...Read more
Genetic disease: Sickle cell disease means the patient inherited the gene for sickle cell disease from both mother and father. The disease is associated with anemia (low blood) and often some degree of jaundice (yellowness.) people with this problem are more likely to be ill with infections early in life and take antibiotics and receive special vaccinations, to help prevent infections. ...Read moreSee 1 more doctor answer
Pain vs weakness: All anemias if bad enough will cause fatigue, weakness, lightheadedness, or shortness of breath with exercise. Sickle cell disease patients are anemic and have these issues, but also have episodes of pain that can occur anywhere in the body (sickle cell crisis) as an additional problem. ...Read more
Gene mutation: Sickle cell trait is caused bu the presence of a single mutation in the beta chain of human hemoglopin a gene. A mutation in one gene on one of a person's two beta globin genes results in sickle cell trait (sa hemoglobin) while the same mutation in both of a persons genes causes sickle cell anemia. (ss hemoglobin). The term trait means a carrier for the sickle cell mutation. ...Read more
Pain.: When red cells sickle, they become rigid and block the flow of blood. If this happens in muscle or bone, the result is pain. In the lung it's pain and shortness of breath. In the brain, it can cause a stroke. Any organ can be effected. A painful crisis happens when blood flow is interrupted. They are episodic and unpredictable. ...Read more
Many.: Basically, sickle cell disease causes disturbance of the blood vessels, typically smaller vessels. Over time, this can cause many problems. Painful episodes, eye problems, lung problems (similar to pneumonia), strokes, decreased spleen function (which can cause severe infections), kidney problems, and other problems. Sickle cell disease is not the same in all people. Some have milder symptoms. ...Read more
Not much: Sickle cell disease is seldom subtle. Patients have intermittent periods of intense pain, often in bone, they have all manifestations of profound anemia, including diminished exercise tolerance, shortness of air, generalized fatigue, etc. This is a very bad disease with few subtle manifestations. ...Read more

Mutated gene: It is believed a single gene mutation occurred hundreds of years ago in a person in sub-Saharan Africa. When carried as one of a pair (trait), it seemed to confer resistance to malaria. It is transmitted as a recessive gene, meaning the normal gene next to it can do the work. When 2 defective genes are present, (sickle cell disease) the proper work is not done and the blood cells are defective. ...Read moreSee 1 more doctor answer
Trait is asymptomatc: A person with as hemoglobin (sickle cell trait is almost always asymptomatic themselves but can pass the mutated gene onto their children. A person with sshemoglobin(sickle cell anemia) is also sometimes asymptomatic, but often develops some symptoms including: anemia, fatigue, pain, slow growth, increased incidence of infection crises, etc. ...Read more
Anemia, pain, crises: The most frequent presenting signs/symptoms of sickle cell include anemia and typical sickle cell crises which include pain crises (severe pain in arms, legs, shoulders, back), acute chest crisis (shortness of breath, cough, fever, lung infiltrate), dactylitis (pain toes/fingers usually as a toddler) and others. Most patients that have sickle cell trait are completely asymptomatic. ...Read moreSee 1 more doctor answer
Symptoms of SS: The altered shape of the red blood cells causes them to stack up together and clog blood vessels, depriving the tissues of adequate blood supply and oxygen. The tissues then die (infarct) and this causes pain. The red cells also rupture or are eaten by the spleen and cause anemia. The spleen itself will gradually infarct, leaving the patient susceptible to infections. ...Read more
Usually none: Having sickle cell trait means being a carrier for a mutation in one of the hemoglobin genes. It usually does not give any symptoms, but is able to be transmitted to ones children. If the other parent also has sickle cell trait or sickle cell anemia, then the children are at risk for possibly inheriting sickle cell anemia. ...Read more
Several: There are several genetic defects that lead to sickle cell anemia. They all lead to a change in the 6th Amino Acid in the beta-globin chain in which valine is substituted for glutamic acid. At least 5 different dna mutations have been identified that all lead to the same Amino Acid substitution, and thus, sickle cell anemia. ...Read more
