    Duchenne muscular dystrophy (DMD) is caused by mutations in the DMD gene, leading to the absence of dystrophin proteins.

  • 2

    Different mutation sites in the DMD gene result in varying loss of dystrophin isoforms, affecting retinal and cognitive functions.

  • 3

    Mouse models of DMD exhibit distinct electroretinogram (ERG) abnormalities correlating with the number of dystrophins lost.

  • 4

    The study aims to establish a genotype-phenotype correlation of retinal dysfunction in DMD using various mouse models.

  • 5

    ERG recordings may serve as a non-invasive method for diagnosing and monitoring CNS-related dysfunctions in DMD.
