Correlating genetic factors with inherited retinal dystrophies

Phenotype Correlates Genotype of Inherited Retina Dystrophies

Observational MejoraVisionMD · NCT03990727

This study is trying to see how the genetic makeup of people with inherited retinal dystrophies, like retinitis pigmentosa, relates to their eye symptoms and family history.

What this trial studies

This observational study aims to correlate the phenotypic characteristics of patients with inherited retinal dystrophies, such as retinitis pigmentosa and cone dystrophies, with their genotypes. It involves conducting ocular examinations, including retina analysis, autofluorescence, and optical coherence tomography (OCT), along with family mapping and blood sample collection for genetic analysis. The goal is to validate the mode of inheritance through segregation analysis, providing insights into the genetic underpinnings of these conditions.

Who should consider this trial

Good fit: Ideal candidates include individuals diagnosed with inherited retinal dystrophies or retinitis pigmentosa who can comply with annual study visits.

Not a fit: Patients who are unwilling or unable to attend annual visits may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance understanding of inherited retinal dystrophies, leading to improved diagnosis and potential future therapies.

How similar studies have performed: Other studies have shown success in correlating genotype with phenotype in retinal dystrophies, indicating that this approach is supported by prior research.
