The genes also play a role in the development and stability of the retina by influencing the structure and function of both the rod photoreceptor cells and supporting cells called the retinal pigmented epithelium. Mutations that affect the normal function of these genes can result in retinitis pigmentosa and resultant vision loss. [citation needed]
The effect of double heterozygous mutations in the genes MITF and PAX3 in WS1 and WS2 can increase the pigment-affected symptoms. It leads to the conclusion that the double mutation of MITF is associated with the extremity of Waardenburg syndrome and may affect the phenotypes or symptoms of the syndrome.
Name OMIM Gene Description Ocular albinism, type 1 (OA1): 300500: GPR143: Also known as Nettleship–Falls syndrome, [4] [5] [6] is the most common variety of ocular albinism. OA1 is usually associated with nystagmus, and difficult to otherwise detect in females; males show more readily observable symptoms.
Neuropathy, ataxia, and retinitis pigmentosa, also known as NARP syndrome, is a rare disease with mitochondrial inheritance that causes a variety of signs and symptoms chiefly affecting the nervous system [1] Beginning in childhood or early adulthood, most people with NARP experience numbness, tingling, or pain in the arms and legs (sensory neuropathy); muscle weakness; and problems with ...
Clinical trials investigating the insertion of the healthy RPE65 gene in retinas expressing the LCA2 retinitis pigmentosa phenotype measured modest improvements in vision; however, the degradation of retinal photoreceptors continued at the disease-related rate. [44] Likely, gene therapy may preserve remaining healthy retinal cells while failing ...
Norrie disease is a rare X-linked recessive genetic disorder that primarily affects the eyes and almost always leads to blindness.It is caused by mutations in the Norrin cystine knot growth factor gene, also referred to as Norrie Disease Pseudoglioma (NDP) gene.
The procedure is a single injection of the AAV2-hRPE65v2 therapeutic gene into the unilateral subretinal of the eye. [39] People must meet the following requirements to be eligible for Luxturna gene therapy: biallelic disease-causing RPE65 mutation, older than one year in age, no surgical contraindications, detectable photoreceptors and RPE ...
Familial exudative vitreoretinopathy (FEVR, pronounced as fever) is a genetic disorder affecting the growth and development of blood vessels in the retina of the eye. This disease can lead to visual impairment and sometimes complete blindness in one or both eyes. FEVR is characterized by incomplete vascularization of the peripheral retina.
