Why the study?

Does the pattern of dystrophin gene deletions correlate with mental retardation in Duchenne muscular dystrophy patients?

Structured PICO

Does the pattern of dystrophin gene deletions correlate with mental retardation in Duchenne muscular dystrophy patients?

Population

162 Duchenne (DMD) patients and two girls with a DMD phenotype (148 mentally assessed)

Intervention

Screening for deletions in the central region of the dystrophin gene with probes cf56a and cf23a

Comparator

Patients with no detectable deletions or deletions not involving exon 52

Outcome

Correlation between mental retardation (MR) and the pattern of deletionsurrogate

Deletions involving exon 52 of the dystrophin gene are significantly associated with mental retardation in patients with Duchenne muscular dystrophy.

No takes yet. Share an insight, caveat, or question.

Supports exploring exon 52 deletions as cognitive risk marker in DMD; leaves open validation before influencing counseling.

Rapaport et al. (1991) studied this question.
