CSIR-CCMB Develops India-Specific Tool to Predict Sickle Cell Severity
ଖବରରେ କାହିଁକି?
Why one beta-globin mutation causes sickle cell, and what CSIR-CCMB's India-specific severity tool changes for GS-III
CSIR-CCMB's new tool predicts sickle cell severity in Indian patients.

Scientists at CSIR-CCMB have developed an India-specific tool to predict the severity of sickle cell anaemia.
Existing international scoring systems do not accurately reflect the clinical profile of Indian patients, and the new tool could improve treatment decisions and disease management.

ମୁଖ୍ୟ ତଥ୍ୟ
Remember these
- CSIR-CCMB (Hyderabad) has developed an India-specific tool to predict sickle cell anaemia severity.
- Existing international severity scores do not reflect the clinical profile of Indian patients.
- Sickle cell anaemia is caused by a point mutation in the beta-globin gene (HBB), producing haemoglobin S.
- It is an autosomal recessive disorder; carriers (sickle cell trait) are usually asymptomatic.
- CCMB, the Centre for Cellular and Molecular Biology, is a CSIR laboratory.

How the exam will ask it
ପ୍ରିଲିମ୍ସ
- Sickle cell anaemia results from a mutation in the beta-globin gene, not the alpha-globin gene.
- Sickle cell anaemia is an inherited autosomal recessive disorder of haemoglobin.
- CSIR-CCMB is a constituent laboratory of the Council of Scientific and Industrial Research and is located in Hyderabad.
ମେନ୍ସ
GS-III Science & Technology and GS-II Health. Issue: international sickle cell severity scores do not fit Indian patients, whose clinical profile differs. Policy: a locally validated predictive tool supports better treatment decisions within national efforts against the disease. Implication: better risk stratification and disease management; way forward: validate the tool across regions and integrate it with screening and tribal health programmes.
Quick recall
Answer before you reveal
Sickle cell anaemia is an inherited blood disorder caused by a mutation in the gene that codes for which part of haemoglobin?
- Alpha-globin chain
- Beta-globin chain
- Gamma-globin chain
- Delta-globin chain
ଉତ୍ତର ଦେଖନ୍ତୁ
ଉତ୍ତର: B — Correct: Beta-globin chain — Sickle cell anaemia results from a point mutation in the beta-globin gene (HBB), producing abnormal haemoglobin S. • Alpha-globin chain — wrong: Alpha-globin gene changes cause alpha-thalassaemia, not sickle cell anaemia. • Gamma-globin chain — wrong: Gamma-globin makes up foetal haemoglobin and is not the site of the sickle cell mutation. • Delta-globin chain — wrong: Delta-globin forms the minor adult haemoglobin A2 and is not the site of the sickle cell mutation.
