Stargardt macular dystrophy and therapeutic approaches

Area of Science:

• Ophthalmology
• Genetics
• Molecular Biology

Background:

• Stargardt disease (STGD1) is the most prevalent inherited macular dystrophy.
• It is an autosomal recessive disorder linked to pathogenic variants in the large ABCA4 gene.
• Significant progress has been made in understanding STGD1's clinical, molecular, and pathophysiological aspects.

Purpose of the Study:

• To review the detailed phenotypic and genotypic characteristics of STGD1.
• To explore the natural history, multimodal imaging findings, and pathogenesis of the disease.
• To summarize current and emerging research and therapeutic interventions for STGD1.

Main Methods:

• Review of clinical and molecular data for STGD1.
• Analysis of multimodal imaging findings and disease natural history.
• Examination of ongoing and planned human clinical trials for novel therapies.

Main Results:

• Detailed characterization of STGD1's phenotypic and genotypic spectrum.
• Understanding of the disease's pathogenesis and natural progression.
• Identification of diverse therapeutic strategies under investigation.

Conclusions:

• Multiple research avenues and therapeutic interventions are being explored for STGD1.
• Novel therapies, including gene replacement targeting the ABCA4 gene, show promise.
• Advancements in understanding STGD1 pave the way for effective treatments.
