Background: The adrenal cortex undergoes constant cellular renewal and any effect from recombinant adeno-associated vectors (rAAV) targeting differentiated cells will be transient as extra-chromosomal DNA will be lost by dividing cells. A novel option is to use rAAV to express ectopic adrenocortical enzymes in a stable organ outside the adrenal gland. Our aim was to correct the biochemical phenotype in a mouse model for congenital adrenal hyperplasia (CAH) wit...
