A nonsense mutation (Gln-673-Term) in exon 17 of the human dystrophin gene detected by heteroduplex analysis.

Heteroduplex analysis was used to search for small mutations in a sample of 40 Italian DMD/BMB patients in whom large rearrangements were not found. A novel nonsense mutation in exon 17 of the dystrophin gene, consisting of a C to T transition, is described.
