The thalassemia trait may confer a degree of protection against malaria[54] which is or was prevalent in the regions where the trait is common, thus conferring a selective survival advantage on carriers known as heterozygous advantagethus perpetuating the mutation.

All people with thalassemia are susceptible to health complications that involve the spleen which is often enlarged and frequently removed and gallstones.

The HSCs then have a beta-globin gene added using a lentiviral vector. Human Genet ; Oxford, Blackwell Scientific Publications, 3rd ed.

The decrease in incidence has benefitted those affected with thalassemia, as the demand for blood has decreased, therefore improving the supply of treatment. Family studies can be done to evaluate carrier status and the types of mutations present in other family members.

Thalassemias are inherited blood disorders characterized by abnormal hemoglobin production. Untreated thalassemia major thalasxemie leads to death, usually by heart failure ; therefore, birth screening is very important.

Multiple thalxssemie transfusions can result in iron overload. American Society of Hematology. Retrieved 7 December It has the benefit of being inexpensive and decent long-term safety. As with about half of all hereditary diseases, [18] an inherited mutation damages the assembly of the messenger-type RNA mRNA that is transcribed from a chromosome.

The primary aim is talassemie bind to and remove iron from the body and a rate equal to the rate of transfusional iron input or greater than iron input.

It represents a potentially toxic iron form due to its high propensity to induce oxygen species and is responsible for cellular damage. In general, poorer populations only have access to limited diagnostic facilities together with blood thalassfmie.

Hemoglobin ; 15 1 et 2: Archived from the original on 25 February In some developing countries, there are virtually no facilities for diagnosis or management of thalassemia.
