Summary
Advanced genetic sequencing methods like optical genome mapping and long-read sequencing can identify Duchenne muscular dystrophy (DMD) structural variants missed by standard genetic tests, aiding in definitive diagnosis.
Area of Science:
- Genetics
- Molecular Biology
- Neuromuscular Disorders
Background:
- Duchenne muscular dystrophy (DMD) is typically diagnosed via genetic testing, identifying variants in up to 98% of cases.
- Standard genetic sequencing failed to diagnose a 5-year-old male with clinical symptoms of DMD, including delayed motor milestones and muscle weakness.
