Can thalassemia develop at the age of 20 years?
Very unlikely. Thalassemia is an inherited disease, affected persons are born with the genetic disorders. However, silent carriers (Alpha Thalassemia, 1 gene defect) or Beta Thalassemia Trait (1 gene defect), do not have significiant symptoms. Consequently, if this person did not have any relevant blood tests till the age of 20, he/she might no be aware of having the condition. That's only a hypothetical suggestion.
In what are there more than two possible alleles for a trait?
gene therapy/ Polygenic trait
What does the term thalassemia minor refer to?
If untreated, beta thalassemia major can lead to severe lethargy, paleness, and delays in growth and development. The body attempts to compensate by producing more blood, which is made inside the bones in the marrow.
Can mild thalassemia be a major thalassemia?
No. A minor form of the blood disorder thalassemia is when you inherited just one beta thalassemia gene, along with a normal beta-chain gene. This manifests as mild anaemia with a slight lowering of the hemoglobin level in the blood. No treatment is require. By contrast, a thalassemia major, also known as Cooley's Disease, is when one is born with two genes for beta thalassemia and no normal beta-chain gene. This is a serious disorder.
What type of study would a psychologist conduct to determine how much of a trait is influenced by genetics?
gene therapy
What does the medical abbreviation hb solu plus rflx frac mean?
This is a type of solubility testing for sickle cell disease. It is very specific for this disease and several combinations sickle cell / thalassemia variants but inadequate for screening and fail to identify important transmissible hemoglobin gene abnormalities - particularly in the prenatal setting when looking for those that affect fetal outcome (eg, Hb C trait, β-thalassemia trait, Hb E trait, Hb B trait, Hb D trait).
Who identified the thalassemia gene?
Dr Thomas Cooley in 1925
What has the author Bakhtaver S Mahajan written?
Bakhtaver S. Mahajan has written: 'New biology and genetic diseases' -- subject(s): Gene therapy, Genetic disorders, Human Genome Project, Human gene mapping, Medical genetics, Thalassemia
Inserting working copies of a gene directly into the cells of a person with a genetic disorder is called what?
Gene TherapyGenetic disorders are caused by an abnormality in person's DNA.
What is a gene trait?
A single-gene trait is a phenotypic trait controlled by two homologous alleles.
WHAT is single gene trait?
A single-gene trait is a phenotypic trait controlled by two homologous alleles.
Why do you need gene therapy?
gene therapy is when a faulty gene is repaired or replaced
