Breakthrough in Research on Inherited Blindness
Breakthrough in Inherited Blindness Research
Researchers at Radboudumc have identified a new genetic cause of retinitis pigmentosa (RP), an eye disease that affects 1 in 5,000 people and can lead to tunnel vision or complete blindness.
They discovered a variant in the RNU4‑2 gene, a non‑coding RNA gene crucial for processing genetic information. Starting with one American family, the team—working with international partners—ultimately provided answers for 153 patients from 67 families worldwide.
The findings highlight the major role of non‑coding DNA in hereditary retinal diseases, opening new avenues for diagnosis, counseling, and future research.
A significant step forward in understanding inherited blindness and expanding the field of genetics.
