Personalized medicine is transforming rare disease treatment by tailoring therapies to an individual’s genetic makeup, lifestyle, and environment. Advances in genomic sequencing, gene and cell therapy, and AI-driven drug development are enabling more precise and effective treatments, offering new hope for patients with previously untreatable conditions. However, challenges such as high costs, regulatory barriers, and limited accessibility remain obstacles to widespread adoption. As biotech innovations continue to evolve, pharmaceutical companies play a critical role in driving research, developing targeted therapies, and improving patient outcomes.
