1. Rare Disorder – Bloom Syndrome
- Bloom Syndrome is a rare genetic disorder with fewer than 300 documented cases globally.
- It severely affects DNA repair mechanisms, leading to abnormal cell growth, developmental delays, and a high predisposition to cancers.
2. Recent Medical Breakthrough in India
- A 12-year-old girl in Chennai recently underwent a bone marrow transplant.
- The procedure used stem cells donated by her younger brother.
- This marks a significant milestone in India’s medical management of rare genetic conditions.
3. Genetic Basis and Inheritance
- The disorder arises from mutations in the BLM gene, which is crucial for DNA replication and repair.
- Inheritance is autosomal recessive, meaning both parents must carry the defective gene for the child to be affected.
- Although most common among the Ashkenazi Jewish population, Bloom Syndrome has been reported worldwide.
4. Broader Significance
- The case highlights India’s growing expertise in advanced genetic therapies and bone marrow transplantation.
- It also raises awareness about the importance of genetic screening and early diagnosis of rare disorders.
