Gene therapy for kidney disease: targeting cystinuria.

PURPOSE OF REVIEW: The aim of this study was to summarize recent findings in kidney gene therapy while proposing cystinuria as a model kidney disease target for genome engineering therapeutics.

RECENT FINDINGS: Despite the advances of gene therapy for treating diseases of other organs, the kidney lags behind. Kidney-targeted gene delivery remains an obstacle to gene therapy of kidney disease. Nanoparticle and adeno-associated viral vector technologies offer emerging hope for kidney gene therapy. Cystinuria represents a model potential target for kidney gene therapy due to its known genetic and molecular basis, targetability, and capacity for phenotypic rescue.

SUMMARY: Although gene therapy for kidney disease remains a major challenge, new and evolving technologies may actualize treatment for cystinuria and other kidney diseases.
