Natural History of PRPF31 Mutation-Associated Retinal Dystrophy
brief summary
The purpose of this study is to characterize the natural history through temporal systemic evaluation of subjects identified with PRPF31 mutation-associated retinal dystrophy, also called retinitis pigmentosa type 11, or RP11. Assessments will be completed to measure and evaluate structural and functional visual changes including those impacting patient quality of life associated with this inherited retinal condition and observing how these changes evolve over time.
detailed description
This is a multi-center, longitudinal, prospective observational natural history study of participants with a molecularly confirmed mutation in PRPF31. Approximately 50 participants (100 eyes) at approximately 5 sites will be enrolled into a uniform protocol for follow-up and evaluations. Each participant's medical record will be reviewed for historical information, and clinical data will be recorded in a secure database. Natural history data will be collected prospectively and will include ophthalmic exams, imaging studies, electrophysiological testing, functional mobility evaluations, and questionnaires. Assessments will be conducted in a standardized protocol every 16 weeks ± 4 weeks for the first year and then every 24 weeks ± 4 weeks for up to approximately 4 years after each participant's baseline visit (Visit 2).
