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 کاملFundus autofluorescence in patients with leber congenital amaurosis.
PURPOSE Fundus autofluorescence (FAF), as an index of lipofuscin accumulation in the retinal pigment epithelium (RPE), provides indirect information on the level of metabolic activity of the RPE and thus the integrity of the RPE/photoreceptor complex. To investigate whether the photoreceptor/RPE complex is still viable in patients with Leber congenital amaurosis (LCA), FAF imaging was performed...
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 کاملDisc oedema in congenital amaurosis of Leber.
Since it was first described by Theodor Leber as 'pigmentary retinitis with congenital amaurosis' (Leber, I867), the entity which bears his name has been the subject of sporadic reports defining its clinical and pathological characteristics. It accounted for about io per cent of the blindness in Sweden (Alstrom and Olsen, 1957) and i8 per cent among children in a series in Holland (SchappertKim...
