Retinol-binding protein 4 has been a drug target for eye diseases as RBP4 is the sole carrier for retinol, which is an essential nutrient for the visual cycle. Animal studies using RBP4-antagonists showed that lowering RBP4 can lead to reduction in the accumulation of lipofuscin that leads to vision loss in eye diseases like Stargardt's disease ...
As previously mentioned, retinol and retinoic acid are modulators of gene expression and are necessary for the proper development and growth of a conceptus. [14] Porcine exhibit a diffuse type placenta that has areolar-gland subunits which allows for transport of larger molecules between dam and fetus.
Retinal gene therapy holds a promise in treating different forms of non-inherited and inherited blindness. In 2008, three independent research groups reported that patients with the rare genetic retinal disease Leber's congenital amaurosis had been successfully treated using gene therapy with adeno-associated virus (AAV).
The first retinal gene therapy to be approved by the FDA was Voretigene neparvovec in 2017, which treats Leber's congenital amaurosis, a genetic disorder that can lead to blindness. These treatments also use subretinal injections of AAV vector and are therefore foundational to research in gene therapy for color blindness. [2] [3]

The gene therapy will compete with Australia-based CSL Behring’s Hemgenix, a similar treatment that won FDA approval for hemophilia B in 2022. That drug has a similar list price of $3.5 million ...
The gene therapy is not a cure for the condition, but substantially improves vision in those treated. [8] It is given as a subretinal injection. Voretigene neparvovec was approved for medical use in the United States in December 2017, [9] in Australia in August 2020, [10] in Canada in October 2020, [11] and in Switzerland in February 2020. [12].
RBP4 has recently been linked to autosomal dominant form of anophthalmia. [4] This form of anophthalmia has variable penetrance and a unique maternal inheritance effect that is rooted in pregnancy. Specifically, the disease only occurs when a mother and fetus both carry a RBP4 mutation which predisposes the fetus to vitamin A deficiency (a ...
