Quick Answer
The DMD gene, which helps make dystrophin, is one of the largest human genes. It spans about 2.2 million base pairs.
The Full Story
The DMD gene is one of the largest known human genes, covering roughly 2.2 million base pairs on the X chromosome. It encodes dystrophin, a protein that helps stabilize muscle cells during contraction. Because the gene is so large, it is especially vulnerable to mutations, which can cause Duchenne and Becker muscular dystrophy. Its size and disease relevance make it one of the best-known examples in medical genetics.
Key Facts
1.DMD spans about 2.2 million base pairs
2.It encodes dystrophin, important for muscle stability
3.Mutations can cause Duchenne and Becker muscular dystrophy
