ABCA4-related retinal problems in African American patients
Stargardt/ABCA4 disease in African Americans
This project looks for genetic changes in the ABCA4 gene and links them to vision problems in African American people with Stargardt-like retinal disease.

What this research studies
If you are an African American with Stargardt-like vision changes or other unexplained macular or retinal disease, this project would collect detailed eye exams and clinical measurements from you. You would also provide genetic testing that looks at both the coding and non-coding parts of the entire ABCA4 gene region. The team will combine the clinical data with laboratory studies of ABCA4 gene variants to understand which changes cause disease. The goal is to fill a knowledge gap because most ABCA4 research so far has focused on people of European descent.
Who could benefit from this research
Good fit: Adults or children of African American descent with suspected or diagnosed ABCA4-related retinopathy (for example Stargardt disease, cone-rod dystrophy, or unexplained macular degeneration) are ideal candidates.
Not a fit: People whose vision loss is caused by non-ABCA4 conditions or who are not of African American descent are less likely to receive direct benefit from this project.
Why it matters
Potential benefit: If successful, this work could make diagnoses more accurate for African American patients and help guide future gene-based treatments.
How similar studies have performed: Genetic and clinical studies in European-ancestry patients have clarified many ABCA4 variants and informed care, but only very small prior studies have included African Americans, so this work is partly building on proven methods and partly novel.
