When studying 300 families with retinitis pigmentosa (RP), researchers found more than 34% of the Hispanic patients exhibited a specific arestin-1 gene mutation—and all of them hail from Southwestern United States. The researchers hope further studies into the gene mutations responsible for RP could lead to individualized gene therapy.
