Complete achromatopsia is a rare autosomal recessive disease associated with CNGA3, CNGB3, GNAT2 and PDE6C mutations. This retinal disorder is characterized by complete loss of color discrimination due to the absence or alteration of the cones function. The purpose of the present study was the clinical and the genetic characterization of achromatopsia in a(More)
INTRODUCTION Mal de Meleda is a rare form of palmoplantar keratoderma, with autosomal recessive transmission. It is characterized by diffuse erythema and hyperkeratosis of the palms and soles. Recently, mutations in the ARS (component B) gene (ARS, MIM: 606119) on chromosome 8q24.3 have been identified in families with this disorder. Congenital cataract is(More)
Central areolar choroidal dystrophy (CACD) is a rare inherited disease, which causes progressive profound loss of vision in patients during their fourth decade. It is characterized by atrophy of retinal pigment epithelium, photoreceptors and choriocapillaris. The disease showed a genetic heterogeneity. Previously, mutations in the peripherin/RDS gene and a(More)
In order to charaterize the Stargardt disease, the molecular exploration of the c.2041C>T mutation (ABCA4 gene) and genotype phenotype correlation in Tunisian patients, seven unrelated propositi underwent a complete ophthalmological examination. The search for the mutation was performed by a direct sequencing after a specific amplification of exon 14 of the(More)
Microspherophakia seems to be the most specific feature of the Weill–Marchesani Syndrome, which could be due to mutations within the ADAMTS10 gene. As the locus responsible for isolated microspherophakia is still unknown, because the reported cases are rare, we checked whether the ADAMTS10 gene is involved in isolated microspherophakia in a Tunisian family.(More)
Hereditary multiple exostoses (HME) is an autosomal dominant orthopaedic disorder most frequently caused by mutations in the EXT1 gene. The aim of the present study is to determine the underlying molecular defect of HME in two multigenerational Tunisian families with 21 affected members and to examine the degree of intrafamilial variability. Linkage(More)
OBJECTIVES Consanguinity is common in Tunisia. However, little information exists on its impact on recessive disorders. In this study, we evaluate the impact of consanguineous marriages on the occurrence of some specific autosomal recessive disorders and consider how other factors, such as population substructure and mutation frequency, may be of equal(More)
BACKGROUND Atrial septal defect (ASD) is an autosomal dominant disease characterized by left-to-right shunting and increased right ventricular output. Approximately 5-10% of congenital heart diseases (CHD) are due to ASD, which is one of the most frequent CHD found in adults. The gene responsible for ASD was mapped to chromosome 5q35 encoding the(More)
PURPOSE To describe the polymorphic expression of Stargardt disease in a large Tunisian family with clinical intra- and interfamilial variation of the condition. METHODS Twelve subjects from two related families with autosomal recessive Stargardt disease were enrolled. A detailed clinical examination including visual acuity and visual field measurement,(More)
