The DMDWarrior Exon Checker helps families interpret DMD genetic test results by analyzing exon deletion or duplication patterns. Enter the first and last affected exon numbers to determine whether the mutation is more likely associated with Duchenne Muscular Dystrophy (DMD) or Becker Muscular Dystrophy (BMD). This free educational tool is designed to help families better understand their genetic reports.Use the DMDWarrior Exon Checker to interpret your DMD genetic test results and learn whether your child's genetic variant is more consistent with Duchenne Muscular Dystrophy (DMD) or Becker Muscular Dystrophy (BMD).

Exon 45–48 Deletion: In-Frame, Often BMD

Under the reading-frame rule (NM_004006.2), an exon 45–48 deletion is in-frame and more often associated with Becker muscular dystrophy (BMD). This is educational, not a diagnosis.

Questions about this exon change

Is an exon 45–48 deletion associated with DMD or BMD?
Under the reading-frame rule (NM_004006.2), this deletion is in-frame and more often associated with Becker muscular dystrophy (BMD). This is educational, not a diagnosis.
Can skipping exon 44, 45, 51 or 53 restore the reading frame after an exon 45–48 deletion?
This tool does not predict that skipping exon 44, 45, 51 or 53 would restore the reading frame for this deletion. Discuss options with a clinician.
