PURPOSE Leber congenital amaurosis (LCA) is the most severe inherited retinopathy with the earliest age of onset. To date, eleven genes have been reported to cause the non-syndromic LCA phenotype. The CEP290 gene has been shown to account for Joubert and Senior-Loken syndromes and to represent a frequent cause of non-syndromic LCA. The aim of the present(More)
PURPOSE X-linked juvenile retinoschisis (XLRS) is one of the most common causes of juvenile macular degeneration in males, characterized by microcystic changes, splitting within the inner retinal layer (schisis), and the presence of vitreous veils. This study was conducted to describe and further correlate specific genetic variation in Spanish patients with(More)
PURPOSE Retinitis pigmentosa (RP) is a genetically heterogeneous group of inherited retinopathies. Up to now, 39 genes and loci have been implicated in nonsyndromic RP, yet the genetic bases of >50% of the cases, particularly of the recessive forms, remain unknown. A novel gene (CERKL) has been described as associated with RP26. It encodes a ceramide kinase(More)
PURPOSE Stargardt disease (STGD), characterized by central visual impairment, is the most common juvenile macular dystrophy. All recessively inherited cases are thought to be due to mutations in the ABCA4 gene. Early-onset autosomal recessive retinitis pigmentosa (arRP) is a severe retinal degeneration that presents before the patient is ten years old. It(More)
BACKGROUND Recessive Dystrophic Epidermolysis Bullosa (RDEB) is a genodermatosis caused by more than 500 different mutations in the COL7A1 gene and characterized by blistering of the skin following a minimal friction or mechanical trauma.The identification of a cluster of RDEB pedigrees carrying the c.6527insC mutation in a specific area raises the question(More)
INTRODUCTION Dominant autosomic ataxias include a group of neurodegenerative diseases characterized by the abnormal expansion of triplets. CASE REPORT Male aged 33, with expansion of the SCA 8 gene (100 repetitions), who presented a clinical picture compatible with a pancerebellar syndrome. The patient had been diagnosed 11 years earlier as suffering from(More)
