Sickle-cell anemia is a genetic disorder that affects the shape and function of red blood cells. In affected individuals, hemoglobin, the protein that carries oxygen, is abnormal, causing red blood cells to become rigid and crescent-shaped. This abnormal shape leads to blockages in blood vessels, resulting in pain, increased risk of infections, and potential organ damage due to reduced blood flow and oxygen supply. Additionally, these sickle-shaped cells have a shorter lifespan, leading to chronic anemia.
African American and Hispanic are greatly affect by sicklecell.

Anemia is the name of the condition. A person with anemia is anemic.
Anemia is caused by a lack of iron in a person's bloodstream. Eating red meat or taking iron supplements can cure anemia.
Pernicious anemia occurs in equal numbers in both men and women

Anemia means low iron in the blood. Kissing is no problem.
If a person has a low red blood cell count, it is an indication that the person is ill. Some conditions that can cause low red blood cell count are kidney disease, cancer, bone marrow disease, and anemia.
The mutation that results in the replacement of glutamate with valine in sickle cell anemia is a missense mutation. This type of mutation occurs when a single nucleotide change in the DNA sequence leads to the substitution of one amino acid for another in the resulting protein. In this case, the specific change involves the codon for glutamic acid being altered to code for valine, which affects the hemoglobin structure and function.
In the case of anemia, or pernicious anemia, this means that the white blood cells have outnumbered the red cells in the body, which would of course give the person a pale, unusually white appearance.
