The latent TGFbeta-binding proteins (LTBPs) and fibrillins are a superfamily of large, multidomain proteins with structural and TGFbeta-signalling roles in the extracellular matrix. Their importance is underscored by fibrillin-1 mutations responsible for Marfan syndrome, but their respective roles are still incompletely understood. We report here on two(More)
Autosomal-recessive Stargardt disease (STGD1) is hallmarked by a large proportion of patients with a single heterozygous causative variant in the disease gene ABCA4. Braun et al. () reported deep intronic variants of ABCA4 in STGD1 patients with one coding variant, prompting us to perform an augmented screen in 131 Belgian STGD1 patients with one or no(More)
Topographic representation of visual fields from the retina to the brain is a central feature of vision. The development of retinotopic maps has been studied extensively in model organisms and is thought to be controlled in part by molecular labels, including ephrin/Eph axon guidance molecules, displayed in complementary gradients across the retina and its(More)
PURPOSE Autosomal recessive retinal dystrophies are clinically and genetically heterogeneous, which hampers molecular diagnosis. We evaluated identity-by-descent-guided Sanger sequencing or whole-exome sequencing in 26 families with nonsyndromic (19) or syndromic (7) autosomal recessive retinal dystrophies to identify disease-causing mutations. METHODS(More)
PURPOSE Optic nerve aplasia (ONA, OMIM 165550) is a very rare unilateral or bilateral condition that leads to blindness in the affected eye, and is usually associated with other ocular abnormalities. Although bilateral ONA often occurs in association with severe congenital anomalies of the brain, nonsyndromic sporadic forms with bilateral ONA have been(More)
Anticoagulant drugs are of great interest to patients and clinical physicians, as well as research scientists. The latter two groups combine their efforts to unravel the related mechanisms of action, as well as means of monitoring and proper dosing. Unfractionated heparin and low molecular weight heparins and vitamin K antagonists have been on board for(More)
Congenital fixed dilated pupils (congenital mydriasis) is characterized by hypoplasia or aplasia of the iris muscles, with absence of iris between the collarette and pupillary border, creating a scalloped pupillary margin. This condition has been reported in a multisystemic smooth muscle cell dysfunction syndrome, combined with congenital patent ductus(More)
The aim of this study was to unravel the molecular pathogenesis of an unusual retinitis pigmentosa (RP) phenotype observed in a Turkish consanguineous family. Homozygosity mapping revealed two candidate genes, SAMD7 and RHO. A homozygous RHO mutation c.448G > A, p.E150K was found in two affected siblings, while no coding SAMD7 mutations were identified.(More)

This article presents a litterature overview of the ophthalmologic secondary effects due to Sabril. First, a review of the visual field loss that can be related to Sabril treatment is presented; the epidemiological and physiopathological aspects of this visual field loss are considered based on experimental and clinical data. The link that can be(More)
PURPOSE Autosomal dominant retinitis pigmentosa (adRP) is characterized by an extensive genetic heterogeneity, implicating 27 genes, which account for 50 to 70% of cases. Here 86 Belgian probands with possible adRP underwent genetic testing to unravel the molecular basis and to assess the contribution of the genes underlying their condition. METHODS(More)
