Deletion/duplication mutations in DMD/BMD identified in Canada

(last modified March 4, 2007)


Studies


Stockley

In total 165 patients were screened, 108 DMD and 57 BMD patients. Of the DMD patients 79 (73%) had a deletion and 12 (11%) a duplication. Of the BMD patients 31 (54%) had a deletion and 3 (5%) a duplication.

Legend
The mutations listed have been published by Stockley et al.2006, determined using quantitative multiplex PCR covering all 79 exons of the DMD-gene. All mutations have been included in the DMD/BMD deletion/duplication database.

Legend
DMD gene deletion/duplication data determined on 181 DMD / BMD patients from Canada. Deletions were described in Gillard et al. (1989); only the 80 of the 109 deletions in the 3' hotspot are shown. Duplications for 72 non-deletion patients were determined by Hu et al. (1990). Analysis was performed using Southern blotting, largely based on the analysis of HindIII and EcoRI-fragments (some also on PstI-digests). All mutations have been included in the DMD/BMD deletion/duplication database.
