Strain Description
Mutations in the RHO gene can lead to rhodopsin-mediated autosomal dominant retinitis pigmentosa (RHO-adRP). In 25% of autosomal dominant inherited RP (adRP) cases, there are over 150 different RHO gene mutations. Notably, the P23H mutation is one of the most prevalent, accounting for 10% of adRP cases. Previous studies have shown that mice carrying the heterozygous human RHO P23H mutation exhibit retinopathy and progressive retinal degeneration similar to the patient's disease process, which could be used for visual signaling and retinitis pigmentosa (RP) studies. This strain is a mouse Rho gene humanized model, in which the endogenous mouse Rho gene and Rho gene promoter are replaced by the human RHO gene carrying a P23H mutation and RHO gene promoter to express human retinal proteins in mice. Therefore, the abnormal protein encoded by the human gene was expressed in mice, resulting in abnormal retinal appearance and function and visual defects in this model.
