This would allow to reveal important information not only to diagnose RP in a patient or family for genetic counseling, but it may also have a predictive value with respect to the likelihood of disease development and choices of therapy (nutrition supplements, drugs, gene replacement strategies, stem cell technologies, etc.) Finally, as new therapies emerge, routine evaluation can keep patients informed of clinical trials and new treatments. Because people with RP have low amounts of PDE6, interaction with a similar enzyme inhibitor harms their eyesight over time eventually resulting in vision loss. [QxMD MEDLINE Link].
