Leber congenital amaurosis caused by mutations in RPGRIP1.
Recessive null mutations in retinitis pigmentosa GTPase regulator interacting protein 1 (RPGRIP1) gene are the cause of LCA6 and account for 5% to 6% of the total patient population. RPGRIP1 has an essential role in the photoreceptor connecting cilia, and photoreceptors lacking RPGRIP1 are unable to maintain the light sensing outer segments. As a result, patients lose retinal functions at an ea...
متن کاملInteraction of nephrocystin-4 and RPGRIP1 is disrupted by nephronophthisis or Leber congenital amaurosis-associated mutations.
RPGR-interacting protein 1 (RPGRIP1) is a key component of cone and rod photoreceptor cells, where it interacts with RPGR (retinitis pigmentosa GTPase regulator). Mutations in RPGRIP1 lead to autosomal recessive congenital blindness [Leber congenital amaurosis (LCA)]. Most LCA-associated missense mutations in RPGRIP1 are located in a segment that encodes two C2 domains. Based on the C2 domain o...
متن کاملLeber congenital amaurosis caused by Lebercilin (LCA5) mutation: Retained photoreceptors adjacent to retinal disorganization
PURPOSE To determine the retinal disease expression in the rare form of Leber congenital amaurosis (LCA) caused by Lebercilin (LCA5) mutation. METHODS Two young unrelated LCA patients, ages six years (P1) and 25 years (P2) at last visit, both with the same homozygous mutation in the LCA5 gene, were evaluated clinically and with noninvasive studies. En face imaging was performed with near-infr...
متن کاملLebers Amaurosis in Three Siblings: A case report
Retinitis pigmentosa (RP) is the generic name for a group of hereditary disorders characterized by progressive loss of photoreceptors and RPE function. The classical triad of retinitis pigmentosa is arteriolar attenuation, retinal bone spicule pigmentation and waxy disc pallor. Lebers congenital amaurosis (LCA) is the hereditary form of retinitis pigmentosa. It presents with blindness either at...
متن کاملIdentification of a novel RPGRIP1 mutation in an Iranian family with leber congenital amaurosis by exome sequencing
Leber congenital amaurosis (LCA) is a heterogeneous, early-onset inherited retinal dystrophy, which is associated with severe visual impairment. We aimed to determine the disease-causing variants in Iranian LCA and evaluate the clinical implications. Clinically, a possible LCA disease was found through diagnostic imaging, such as fundus photography, autofluorescence and optical coherence tomogr...
