Abstract

Non syndromic forms of Retinitis Pigmentosa (RP) constitute a collection of clinically and genetically heterogeneous inherited retinal degenerative diseases. They are characterized by a bilateral progressive visual loss susceptible to cause blindness. These diseases are transmitted through pedigrees according to all known modes of inheritance. They are bilateral and usually start during infancy. However, very early clinical presentations exist, such as those observed in children affected by Leber Congenital Amaurosis, as well as late onset autosomal dominant forms of retinitis pigmentosa. The characteristic clinical aspect of the rod-cone RP dystrophies is marked by alterations of the peripheral retina associated with a night blindness and a progressive narrowing of the visual field. The ophthalmoscopic examination of RP patients commonly reveals thin retinal arteries and scattered pigmentary accumulations. In contrast, there are cone rod retinal dystrophies whose onset is marked by a decreased visual acuity before the appearance of any visual field alteration. Some forms of RPs display an ocular fundus devoid of any pigmentary alteration. Syndromic forms of RPs are not uncommon. The association of deafness with RP is detected ...Continue Reading

CREs: Gene & Cell Therapy

Gene and cell therapy advances have shown promising outcomes for several diseases. The role of cis-regulatory elements (CREs) is crucial in the design of gene therapy vectors. Here is the latest research on CREs in gene and cell therapy.
