LRAT

Lecithin retinol acyltransferase; essential for the visual cycle (same pathway as RPE65)

Aktif Klinik Çalışmalar

LRAT-LCA shares the visual-cycle defect of RPE65, so it was targeted with an oral synthetic retinoid (QLT091001 / zuretinol acetate) rather than gene therapy. A Phase 1b trial in RPE65- or LRAT-deficient LCA/RP reported transient improvements in visual field and acuity (Koenekoop et al., Lancet 2014). A later Phase 2/3 trial was withdrawn and no therapy is approved. AAV LRAT gene therapy has not entered clinical trials.
