For example, in Nigeria, by far the most populous country in the subregion, 24% of the population are carriers of the mutant gene and the prevalence of sickle-cell anaemia is about 20 per 1000 births. (who.int)
This means that in Nigeria alone, about 150 000 children are born annually with sickle-cell anaemia. (who.int)
The public health implications of sickle-cell anaemia are significant. (who.int)
When health impact is measured by under-five mortality, sickle-cell anaemia contributes the equivalent of 5% of under- five deaths on the African continent, more than 9% of such deaths in west Africa, and up to 16% of under-five deaths in individual west African countries. (who.int)
There are, however, no firm data on the survival of patients with sickle-cell anaemia on the African continent. (who.int)
Sickle-cell anaemia covers a wide spectrum of illness. (who.int)
While IAEMH is associated with severe anaemia due to intravascular haemolysis caused by red cell invasion, oxidative injury, auto-antibodies, and/or pathogen-haem interaction, IAIMH is associated with haemophagocytic tri-lineage destruction of haematopoietic precursors in the bone marrow.

A trait carrier is healthy, but can pass the sickle gene to their children. (sicklecellspeaks.com)
The inheritance of one gene for normal hemoglobin (A), and one gene for hemoglobin (C). A person who has hemoglobin C Trait (AC) is a carrier of the hemoglobin C gene, and is not affected by the gene. (mo.gov)

Sickle cell hemoglobinopathy encompasses a group of inherited genetic disorders, which cause erythrocytes to become sickled and affect multiple organ systems. (medscape.com)

Millions of people worldwide are affected by the sickle cell blood disorder. (pfizer.com)
Do you or your child have a platelet, bleeding, or white blood cell disorder? (nih.gov)
To participate in this study, you must be a child or adult who either is healthy or has a platelet disorder, coagulation disorder, or white blood cell disorder. (nih.gov)
To prevent the abnormal sickle gene from being passed to offspring, we must intervene earlier, help people understand the danger of this disorder, and encourage testing for the hemoglobin gene traits in at-risk ethnic groups. (medstarhealth.org)

In rare cases, some people with the trait may experience a complication. (fountainvalleyhospital.com)

SCD affects cells so that they become crescent- or sickle-shaped instead of being rounded, and they become less rigid than those in people without the condition. (medicalnewstoday.com)

Hematuria Hyposthenuria Renal medullary carcinoma, a cancer affecting the kidney, is a very rare complication seen in patients with sickle cell trait. (wikipedia.org)
Some sickle cell patients will sustain enough damage to their spleen that it becomes shrunken and ceases to function at all. (healthline.com)
Chronic pain is the most common cause of poor quality of life in sickle patients. (medstarhealth.org)

Taubenberger's autopsy results showed that the soldier had had a sickle-cell crisis that contributed to his death even though he had only one copy of the gene. (wikipedia.org)

Adults can also get tested, such as immigrants from high-prevalence areas who were not tested at birth, or anyone who never found out their results (even though all parents are always told if their baby is positive for SCD, this doesn't always happen for babies with Trait). (diagnosis123.com)

As the sickle cells clog the blood vessel, they can block blood flow to various parts of the body, causing painful episodes (known as sickle cell crises) and raise the risk of infection. (pfizer.com)
Painful or damaging blockages are called sickle cell crises. (healthline.com)
These clots give rise to recurrent painful episodes called "sickle cell pain crises. (health.am)
Sickle cell trait does not cause painful crises, but rarely, people die suddenly while undergoing very strenuous exercise that causes severe dehydration, such as during military or athletic training. (msdmanuals.com)

Universal neonatal screening for sickle cell haemoglobin at the national level should be considered. (who.int)

However, individuals with sickle cell trait may have rare complications. (wikipedia.org)
The ophthalmologist should also be made aware that the person has SCT since some medications used to treat increased intraocular pressure might cause sickling complications in individuals with SCT. (cdc.gov)
Previous large-scale genome-wide association studies carried out in largely healthy individuals have identified thousands of variants associated with HT, which have then been used to develop multi-ancestry polygenic trait scores (PTS). (haematologica.org)
Rarely, extreme conditions such as severe dehydration and high-intensity physical activity can lead to serious health issues, including sudden death, for individuals with sickle cell trait. (onescdvoice.com)

People with sickle cell trait have inherited a sickle cell gene from one parent and a normal gene from the other parent. (sicklecellspeaks.com)

He was diagnosed with the sickle cell trait, and his production dropped off in both 2016 (39 catches, 517 yards, two touchdowns) and 2017 (21 catches, 299 yards, three touchdowns). (baltimoreravens.com)
Brown believes a cyst on his spine in 2016 caused the root of his problems in Arizona, not the sickle cell trait, which can cause carriers to suffer muscle breakdown while doing intense exercise. (baltimoreravens.com)

Sickle cell trait is a hemoglobin genotype AS and is generally regarded as a benign condition. (wikipedia.org)

Translocation carcinoma is a renal cell carcinoma (RCC) subtype that harbors a translocation involving a member of the microphthalmia transcription factor gene family. (medscape.com)
Translocation-associated renal cell carcinomas (RCCs) arise from the proximal tubule epithelium, similar to conventional clear cell and papillary RCCs. (medscape.com)
Xp11.2 translocation-associated renal cell carcinomas are generally cortical or subcapsular, well-circumscribed lesions with yellow-tan, variegated cut surfaces. (medscape.com)
In Xp11.2 translocation-associated renal cell carcinoma (RCC), cells typically have voluminous cytoplasm, which can range from eosinophilic and granular to clear. (medscape.com)
Xp11.2 translocation-associated renal cell carcinomas (RCCs) may have well-developed papillae, mimicking papillary RCCs. (medscape.com)
In Xp11.2 translocation-associated renal cell carcinoma, tumor cells with abundant eosinophilic cytoplasm and high nuclear grade are often arranged in large nests with a delicate, intervening vascular stroma. (medscape.com)
The nests of tumor cells in Xp11.2 translocation-associated renal cell carcinomas may become centrally discohesive, giving rise to a pseudoalveolar growth pattern. (medscape.com)

If you have only one copy of the gene, you are said to have sickle cell trait. (healthline.com)
