Accurate and timely diagnosis, anchored by comprehensive genetic testing, is an increasingly crucial element of the Retinitis Pigmentosa (RP) treatment paradigm. Given that the only approved curative treatment (Luxturna) is gene-specific, identifying the causative mutation is the critical first step to determining a patient's eligibility for current and pipeline gene therapies. The use of large-panel Next-Generation Sequencing (NGS) allows clinicians to rapidly screen for the over 100 known RP-related genes, enabling a faster and more personalized treatment decision.

Beyond eligibility for gene replacement, the genetic diagnosis informs prognosis and allows for patient enrollment in appropriate clinical trials. For example, knowing a patient has a severe X-linked form (RPGR) guides them toward the specific therapies in development for that gene. The availability of increasingly affordable and accessible genetic screening tools is fundamental to leveraging the scientific progress in specialized treatments.

The diagnostics segment, encompassing genetic counseling, screening, and confirmation, is intrinsically linked to the high-value specialized therapeutics. As the pipeline of gene-specific drugs matures, the demand for timely, accurate genetic intelligence will continue to fuel this foundational area of the Retinitis Pigmentosa Treatment Market.

FAQ 1: Why is genetic testing essential for modern RP treatment? Genetic testing is essential because the first and only approved curative therapy, and many pipeline treatments, are gene-specific, meaning they only work for patients with a particular mutation.

FAQ 2: What does NGS (Next-Generation Sequencing) do in RP diagnostics? NGS is a technology that rapidly and simultaneously analyzes all 100+ known RP-causing genes, enabling a quick and comprehensive identification of the specific mutation responsible for the patient's condition.
