Sickle-Cell Disease

Sickle Cell Disease is a blood disorder that is permanent. It is a lifelong struggle for those who have it. Those suffering from the disease need to take a variety of medications in order to maintain their health and survive.

Yes, but the mutation happened many many thousands of years ago. It has been passed on through all these generations because the same gene that causes sickle cell anemia in a person that inherits two copies of the gene also causes resistance to the malaria parasite in a person that inherits only one copy of the gene.

In areas of the world where malaria is a common disease, the resistance to it is a stronger selective advantage than sickle cell anemia is a selective disadvantage; so the gene becomes very common in those populations.

lol that's a dumb question

and that's a dumb answer. Yes it is always possible, to some tiny degree. The risk factor is dependent on the specific races involved. For example a person of African decent has a higher risk, than a person of hispanic or Mediterranean, and caucasian is the lowest risk of all. If one parent is caucasian the risk is pretty small. among 2 caucasians, not of middle eastern or Mediterranean, non jewish, the risk is smallest.

It is when your body does not produce alot of blood and you become very skinny and sick. It can be passed on to babies by mothers and mostly occurs in African countries and some parts of Asia, too.

That is very interesting question, indeed. Your concern for the primates needs appreciation. The answer to this question is probably positive. Sickle cell anaemia is a natural selection in malaria endemic zone. The sickle cell trait patient is genetically resistant to malarial fever. So many primates suffer from malarial fever. From this finding you can say that sickle cell anaemia should be present in primates, who live in tropical countries.

They are both genetic blood disorders, which are inherited from the parents.

Sickle cell anemia is caused by a mutation in the gene responsible for hemoglobin. If a person has inherited the mutation, their bone marrow will produce sticky, sickle-shaped red blood cells, which cause a wide array of issues.

Hemophilia is another blood disorder that is inherited from the parents, but in a different and more complicated way. Hemophiliacs (people suffering from hemophilia) have a problem with blood clotting. They will always bruise easily, and when they bleed, the blood might not clot unless certain actions are taken.

Both diseases affect the blood, and are life long. There are currently no effective cures for them.

My brother had iron-deficiency anemia as a kid and he had to take pills to help raise his iron-levels. There are also iron-filled foods that can raise the level naturally, including beans and spinach. (It wasn't Popeye's source of strength for no reason.)

The parents are both recessive (Ss) for sickle cell anemia.

Because the spleen is responsible for destruction of abnormal red blood cells; therefore since sickle cell causes abnormalities in red blood cells, the spleen works extra hard for extended periods of time to remove them.

Sickle cell trait carries a lower risk of serious malarial disease, without the signs and symptoms of sickle-cell anemia.

Sickle cell appears in several geographical regions in the world and is attached to different genes in those areas. It appears where malaria is endemic. The African form is the most common. Different forms developed in Southern Greece, Southern Afghanistan, and a few other places. The African form affects Black people.

Sickle cell anemia is a genetic diseases that causes red blood cells to be shaped like sickles while normal red blood cells are shaped more like a cylinder. Malaria works by going into the red blood cells until they burst. Because of the strange shape of the red blood cells in people who have sickle cell anemia, malaria can't enter in the cells that have the sickle trait, but it can enter in the others. This way, people with sickle cell wouldn't be as adversely effected then those without it.

The person is homozygous for the trait

people with sickle cell disease have no abnormal appearances. the abnormalities are found on the microscopic level when the blood cells are examined.

it is dangerous because it messes up your depth perception.

Alcohol alters your brain so your not always in control.

Alcohol alters your ability to drive.

Alcohol causes liver damage and loss of brain cells.

A person can only inherit sickle-cell genes if some of their ancestors came from certain regions in Africa where the inhabitants carry sickle-cell genes.

A person with one sickle-cell gene has sickle-cell trait, a milder problem.

If both father and mother pass on sickle-cell genes, the child, with two genes, will have sickle-cell disease.

In the cold seasons the patient will suffer from joint pains, and in the high places like mountain they will suffer also from severe pain.

sickle cell orignates when a red blood cell is too large to fit in the blood vessel and the pressure that is against the it causes it to have a crescent shape
