Sickle Cell Disease

Prevalence: ~300,000 births/year worldwide, predominantly in Sub-Saharan Africa, Mediterranean, Middle East, India

A monogenic disorder caused by the HBB rs334 (Glu6Val) mutation in beta-globin. Hemoglobin S polymerizes under deoxygenation, causing vaso-occlusive crises, chronic hemolysis, and organ damage. Gene therapy and anti-sickling approaches are transforming treatment.

Peptide Therapeutics

Anti-sickling peptides blocking HbS polymerization contacts, fetal hemoglobin-inducing peptides, anti-adhesion peptides preventing vaso-occlusion, and cell-penetrating peptide delivery of gene editing machinery.

Current Treatments

Hydroxyurea, voxelotor, crizanlizumab, L-glutamine, gene therapy (Casgevy, Lyfgenia). Blood transfusions for acute crises.
