Genetic testing plays an important role in diagnosing Duchenne Muscular Dystrophy and understanding changes in the DMD gene that cause the condition. It helps healthcare professionals confirm a diagnosis, identify carriers, and support informed medical and family planning decisions. Different testing methods may be recommended depending on symptoms, family history, and previous test results. Genetic counseling is often included to explain findings and discuss possible implications for patients and relatives. Understanding the testing process can help families make informed decisions while supporting appropriate medical care, ongoing monitoring, and access to relevant resources for long term health management and planning.
