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 45–50 Deletion: Exon 51 Skip May Restore Frame

Under the reading-frame rule (NM_004006.2), an exon 45–50 deletion is out-of-frame and more often associated with Duchenne muscular dystrophy (DMD). Skipping exon 51 may restore the frame. Educational only — a clinician must confirm eligibility.

Questions about this exon change

Is an exon 45–50 deletion associated with DMD or BMD?
Under the reading-frame rule (NM_004006.2), this deletion is out-of-frame and more often associated with Duchenne muscular dystrophy (DMD). This is educational, not a diagnosis.
Which exon skipping is suitable for an exon 45–50 deletion?
Skipping exon 51 would restore the reading frame for this deletion. This is educational information, not a prescription; a clinician must confirm eligibility. RNA splicing exceptions exist.
