Presentation
In contrast, homozygous Hb E patients do not usually manifest infections. [4] In the present case, the patient presented with low-grade fever and anemia and while investigating him, coexistent mycobacterium tuberculosis infection was revealed along with [ijpmonline.org]
In both of these S/Aß classifications, the clinical picture correlates with the percentage of hemoglobin S present. S/Aß0 is also a common presentation in the Mediterranean, Iranian, and Chinese/Southeastern Asian ethnic groups. [clinicaladvisor.com]
With no deletions, there is approximately 20% HbG, with one deletion about 30% G is present, and with two about 40% is present. *** Also known as D Punjab (same mutation) # Not a mutation, Lepore is the product of the indicated crossover during meiosis [wardelab.com]

Asymptomatic
The other reason is that Hb E disease is mostly asymptomatic; therefore, its association with tuberculosis may not be revealed. [ijpmonline.org]
One or two genes affected: Asymptomatic or discreet symptomatology. [atlasgeneticsoncology.org]
Thalassemia minor is clinically asymptomatic but some subjects may have moderate anemia. [ncbi.nlm.nih.gov]
α thalassaemia homozygous (genotype α,-/α,-): slightly anaemic, low MCV and MCH; clinically asymptomatic. αo thalassaemia heterozygous (genotype α,α/,--): slightly anaemic, low MCV and MCH; clinically asymptomatic. [patient.info]
Hypochromic microcytes and target cells are the main features in asymptomatic individuals. [clinlabnavigator.com]

Falling
Hemoglobin F production falls dramatically after birth, although some people continue to produce small amounts of hemoglobin F for their entire lives. Clinically Significant Variant Hemoglobins Hemoglobin S. [sickle.bwh.harvard.edu]
The carriers of thalassemia have a partial immunity against malaria infections and the blood cells fall down not allowing time for development of the malaria microbe. [synevo.com.tr]
Because of the sickling, the patients suffer a chronic hemolytic anemia and the usual 120 day half life of erythrocytes falls to a mere 20 days for patients with sickle disease. [wardelab.com]
There is normal or decreased ejection fraction on cineangiogram at rest, and it falls on exercise. The 24-hour ECG reveals atrial and ventricular premature beats, often in pairs or in runs. [patient.info]
It is the primary hemoglobin produced by the fetus during pregnancy ; its production usually falls shortly after birth and reaches adult level within 1-2 years. [labtestsonline.org]

Sickle/beta-thalassemia is the most common sickle syndrome seen in people of Mediterranean descent (Italian, Greek, Turkish). Beta-thalassemia is quite common in this region, and the sickle cell gene occurs in some sections of these countries. [sickle.bwh.harvard.edu]
In Sri Lanka, it can reach up to 40% and affects those of Sinhalese and Vedda descent. [9] [10] It is also found at high frequencies in Bangladesh and Indonesia. [11] [12] The trait can also appear in people of Turkish, Chinese and Filipino descent. [ [en.wikipedia.org]

Severe Pain
Some examples include: Weakness, fatigue Lack of energy Jaundice Pale skin (pallor) Some serious signs and symptoms include: Episodes of severe pain Shortness of breath Enlarged spleen Growth problems in children Upper abdomen pain (due to stone formation [labtestsonline.org]
An abnormally enlarged spleen (splenomegaly) can cause severe pain and contribute to anemia. Splenomegaly can cause low levels of the blood cells (platelets) that allow the blood to clot. [rarediseases.org]

Increased Susceptibility to Infections
Risks associated with splenectomy include an increased susceptibility to infections mainly from encapsulated bacteria ( Streptococcus Pneumoniae, Haemophilus Influenzae and Neisseria Meningitidis ) and an increase in thromboembolic events. [ojrd.biomedcentral.com]

Workup
We routinely screen all couples for hemoglobin alpha (HBA) gene deletions when performing molecular workup for beta thalassemia prenatal diagnosis. [ashclinicalnews.org]
Clinical Testing and Workup Physicians will take a blood sample from individuals suspected of having beta thalassemia. Several different tests can be performed on a single blood sample. [rarediseases.org]
This study supports the integration of broad unbiased genetic screening into the diagnostic workup of children and young adults with bone marrow failure and myelodysplastic syndromes. [profiles.stanford.edu]

Prognosis
Prognosis for individuals with beta-thalassemia has improved substantially in the last 20 years following recent medical advances in transfusion, iron chelation and bone marrow transplantation therapy. [ncbi.nlm.nih.gov]
Prognosis The prognosis depends on the severity of the disease and adherence to treatment: α thalassaemia The prognosis is excellent for asymptomatic carriers. The overall survival for HbH disease is good overall but variable. [patient.info]
Prognosis For silent carriers and individuals with alpha thalassemia trait, the prognosis is excellent. For individuals with HbH disease, the overall survival rate varies but is generally good, with most patients surviving into adulthood. [emedicine.medscape.com]
Prognosis Prognosis of thalassemia minor subjects is excellent. An increased risk for cholelithiasis, especially in association with the Gilbert mutation has been demonstrated [ 92 ]. [ojrd.biomedcentral.com]
Prognosis As discussed above, the prognosis for individuals with the most serious types of thalassemia has improved drastically in the last several years following recent medical advances in transfusion, chemo-, and transplantation therapy. [medical-dictionary.thefreedictionary.com]

Prevention
Also, genetic surveys are appropriate in requests for preventive studies. These surveys cover the prenatal diagnosis and determination of the fact whether the relatives and children of those diagnosed with thalassemia are carriers or not. [synevo.com.tr]
Since thalassemia is a genetic disorder, there’s no way to prevent it. However, there are ways you can manage the disease to help prevent complications. [healthline.com]
This helps scientists look for better ways to prevent and treat thalassaemia. You can opt out of the register at any time. [nhs.uk]
Prevention This disease is inherited. Blood tests and family genetic studies will show if you are a carrier. A genetic counselor can discuss the risks of passing on the disease. References: Explore thalassemias. [cancercarewny.com]
