Precision medicine is transforming the way rare genetic diseases are diagnosed and managed by tailoring healthcare to an individual's genetic profile. Advances in genomic sequencing, molecular diagnostics, and targeted therapies allow healthcare professionals to identify the underlying causes of many rare conditions with greater accuracy. This personalized approach supports earlier diagnosis, informed treatment planning, and improved patient monitoring. Although challenges such as accessibility, cost, and limited treatment options remain, ongoing research continues to expand possibilities for patients and families. Understanding precision medicine helps individuals recognize its role.
