People with one copy of the gene for hemoglobin C (termed heterozygous) do not experience significant symptoms, but can pass the abnormal gene onto their children; this condition is called hemoglobin C trait. When two hemoglobin C genes are present (termed homozygous), the individual is said to have hemoglobin C disease, and may develop mild ...
Hemoglobin electrophoresis is a blood test that can detect different types of hemoglobin. The test can detect hemoglobin S, the form associated with sickle cell disease, as well as other abnormal types of hemoglobin, such as hemoglobin C. It can also be used to investigate thalassemias, which are disorders caused by defective hemoglobin production.
Sickle cell trait is a hemoglobin genotype AS and is generally regarded as a benign condition. [1] However, individuals with sickle cell trait may have rare complications. For example, in November 2010, Dr. Jeffery K. Taubenberger of the National Institutes of Health discovered the earliest proof of sickle-cell disease while looking for the ...
Hemoglobinopathy is the medical term for a group of inherited blood disorders involving the hemoglobin, the protein of red blood cells. [1] They are generally single-gene disorders and, in most cases, they are inherited as autosomal recessive traits.
In medical genetics, compound heterozygosity is the condition of having two or more heterogeneous recessive alleles at a particular locus that can cause genetic disease in a heterozygous state; that is, an organism is a compound heterozygote when it has two recessive alleles for the same gene, but with those two alleles being different from each other (for example, both alleles might be ...
Caroline C. Boyle, USA TODAY. ... red blood cell count (RBC), hemoglobin (HGV) and hematocrit (HCT). In general, these indicators all have “slightly different ways of measuring the same thing ...
Hemoglobin variants occur when there are mutations in specific genes that code for the protein chains, known as globins, which make up the hemoglobin molecule. This leads to amino acid substitutions in the hemoglobin molecule that could affect the structure, properties, and/or the stability of the hemoglobin molecule.
People with Hemoglobin D trait do not have health problems related to having the trait. People with hemoglobin D trait do not have Hemoglobin D disease or sickle cell disease. They cannot develop these diseases later in life. While Hemoglobin D can be detected without a DNA test, one is needed to ascertain that a person who carries Hemoglobin D ...
