An Observational Study of Japanese Participants With X-linked Retinitis Pigmentosa

X-Linked Retinitis Pigmentosa Clinical Trial

Official title:
Prospective Observational Study to Estimate the Genotype and Phenotype of Japanese Patients With X-linked Retinitis Pigmentosa Associated With Pathogenic Variants in Retinitis Pigmentosa GTPase Regulator (RPGR)

Clinical Trial Summary

The purpose of the study is to identify a cohort of Japanese participants with X-linked retinitis pigmentosa (XLRP) associated with pathogenic variants in the retinitis pigmentosa GTPase regulator (RPGR) gene and to investigate their associated phenotype.
