Sickle-cell disease (SCD), or sickle-cell anaemia or drepanocytosis, is an autosomal co-dominant genetic blood disorder characterized by red blood cells that assume an abnormal, rigid, sickle shape.

Mutation that causes sickle cell anemia?

Sickle cell anemia is caused by a mutation in the gene that encodes for the beta-globin chain of hemoglobin. This mutation results in the production of abnormal hemoglobin molecules (hemoglobin S), leading to the characteristic sickle shape of red blood cells.


Is sickle cell disease recessive?

Yes, Sickle Cell-Anemia is a genetic condition that is passed down from one generation to the other.


Which types of mutation causes sickle cell anemia?

Sickle cell anemia is caused by a point mutation in the HBB gene, specifically a substitution of adenine for thymine in the sixth codon of the gene, resulting in the production of abnormal hemoglobin known as hemoglobin S.


What disorder does a mutation in hemoglobin cause?

Sickle cell anemia.


What disorder does mutation in the hemoglobin cause?

Sickle cell anemia.


What type of mutation cause cell anemia?

Mutations in the hemoglobin molecules cause sickle cell anemia.


What is a genetic disorder that causes abnormal hemoglobin?

Sickle cell anemia causes sickle-shaped red blood cells. It is caused by a single base pair gene mutation.


The mutation that results in sickle cell anemia produces effects that are?

The mutation that causes sickle cell anemia leads to the production of abnormal hemoglobin, which causes red blood cells to become sickle-shaped. These sickle-shaped cells can block blood vessels, impairing blood flow and leading to episodes of pain, tissue damage, and increased risk of infections.


What type of mutation causes sickle cell anemia substitution deletion insertion mutagen?

The type of mutation that causes a defect in the gene (causing sickle cell anaemia) is a substitution mutation.A single nucleotide substitution (A to T) in the β-globin gene causes the amino acid valine to replace glutamic acid. This changes the resulting protein, causing a haemoglobin with an abnormal shape to be created.
