BIRSA 101 | 20 Nov 2025

Why in News?

The Minister of Science & Technology has launched “BIRSA 101”, India’s first indigenous CRISPR-based gene therapy for Sickle Cell Disease.

  • Named after  Birsa Munda on his 150th birth anniversary (15th November 2025), the therapy strengthens India’s push for a “Sickle-Cell-Free Nation,” with significant benefits for affected tribal communities in central and eastern India.

Key Points

  • About BIRSA 101:
  • About CRISPR Gene Editing:
    • CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) is a naturally occurring defence mechanism found in bacteria, used to cut viral DNA.
    • Modern gene-editing uses CRISPR–Cas9, where Cas9 functions like molecular scissors to cut DNA at specific target sites.
    • It enables precise, efficient, and low-cost genome editing, making it a major breakthrough in biotechnology and medical research.
    • First demonstrated as a gene-editing tool in 2012, pioneered by Jennifer Doudna and Emmanuelle Charpentier, who received the 2020 Nobel Prize in Chemistry.
  • About Sickle Cell Disease (SCD):
    • Sickle Cell Disease is an autosomal recessive genetic blood disorder caused by an HBB gene mutation, producing abnormal Hemoglobin-S that makes red blood cells sickle-shaped and rigid. This leads to anemia, pain crises, infections, and organ complications.
    • It is highly prevalent in tribal communities of central and eastern India and is a focus area under the National Sickle Cell Anaemia Elimination Mission (2023–2047).
    • Conventional treatment includes hydroxyurea, blood transfusions, and stem-cell transplant.
