Researchers from the National Eye Institute have developed a gene therapy that rescues cilia defects in retinal cells affected by a type of Leber congenital amaurosis (LCA), a disease that causes blindness in early childhood. Using patient-derived retina organoids (also known as retinas-in-a-dish), the researchers discovered that a type of LCA caused by mutations in the NPHP5 (also called IQCB1) gene leads to severe defects in the primary cilium, a structure found in nearly all cells of the body.
The findings not only shed light on the function of NPHP5 protein in the primary cilium but also led to a potential treatment for this blinding condition. NEI is part of the National Institutes of Health.
"It's so sad to see little kids going blind from early onset LCA. NPHP5 deficiency causes early blindness in its milder form, and in more severe forms, many patients also exhibit kidney disease along with retinal degeneration," said the study's lead investigator, Anand Swaroop, Ph.D., senior investigator
