Facts
about Hemoglobin
- Hemoglobin
is found in the red blood cells and is the oxygen carrier of the blood.
- The
type of hemoglobin we have is determined by inheritance.
- There
are over 400 different types of abnormal hemoglobins (hemoglobinopathies)
found both in the black and white population.
- People
who inherit one normal gene (A) for hemoglobin and one abnormal gene
(?) for hemoglobin are known as hemoglobin trait carriers.
- The
most common abnormal hemoglobins found in the black population are
Hemoglobin S and Hemoglobin C.
- 1 out
of 10-12 African Americans carries the gene for Hemoglobin S (AS)
- Sickle Cell Trait.
- 1 out
of 40 African Americans carries the gene for Hemoglobin C (AC) - Hemoglobin
C Trait.
- Usually
trait carriers are not sick, they can live a healthy, normal life.
- Individuals
must have a special hemoglobin test to determine if they may be trait
carriers.
- Sickle
Cell Trait carriers will not develop Sickle Cell Disease but may pass
it on to their offspring.
- If both
parents are Sickle Cell Trait carriers, each time a child is born
there is a 25% chance the child will have some variant of Sickle Cell
Disease.
- Sickle
Cell Disease has many known variants.
- Sickle
Cell Anemia (SS) affects 1 out of 500 African Americans.
- Sickle
Cell Hemoglobin C Disease (SC) affects 1 out of 800 African Americans.
- Over
50,000 African Americans are victims of Sickle Cell Diseases.
- Sickle
Cell Disease is incurable at the moment.
- A person
with Sickle Cell Disease can live a productive, useful life if they
take care of themselves and visit the doctor regularly.
- If you
are old enough to be the parent of a child you should know your hemoglobin
type.
- You
may obtain a hemoglobin test, free of charge, at the Sickle Cell Foundation
of Greater Montgomery.
