Generation of isogenic gene-corrected cell lines from a USH2A-RP patient-derived iPS cell line.

Gene editing created isogenic USH2A-RP patient-derived iPSC lines with both homozygous and heterozygous corrections of the c.2276G > T mutation.

• Why it matters: Genetic background differences can confound studies comparing patient and control iPSCs, limiting understanding of disease-specific effects.
• What they did: Researchers used precise gene editing to generate gene-corrected control lines from a USH2A-RP patient iPSC line, producing both homozygous and heterozygous corrected cells.
• The result: These isogenic lines will enable investigation of RP phenotypes linked to the USH2A mutation in disease-relevant cell types.
