The present study examined academic skills in children and young adults with infantile nephropathic cystinosis. Cystinosis is a genetic metabolic disorder in which the amino acid cystine accumulates in various tissues and organs, including the kidney, cornea, thyroid, and brain. Individuals with cystinosis have normal intelligence but subtle visual processing impairments. Subjects were 19 child...
Infantile nephropathic cystinosis is a genetic metabolic disorder in which the amino acid cystine accumulates in various organs, including the kidney, cornea, thyroid, and brain. Despite normal intellect, individuals with cystinosis may have specific impairments in the processing of visual information. To examine further the specific types of deficits in visual processing found in individuals w...
Cystinosis is an autosomal recessive disease in which three clinical forms are recognized: infantile nephropathic, with renal tubular damage by 1 year of age and progressive glomerular insufficiency; intermediate, with tubular and glomerular insufficiency beginning at a later age; benign, with no kidney damage. Skin fibroblasts cultured from patients with all types of cystinosis show increased ...
OBJECTIVE To analyze the fertility status in adult, male cystinosis patients treated with cysteamine. Cystinosis is an autosomal recessive disease leading to intralysosomal cystine accumulation. Worldwide, a few female cystinosis patients have given birth. However, no male cystinosis patients are known to have induced pregnancy. Adequate cysteamine treatment might improve male fertility. PATI...
BACKGROUND Cystinosis is an autosomal recessive disease characterised by the abnormal accumulation of lysosomal cystine. Mutations in the cystinosin gene (CTNS) represent known causes for the disease. The major cystinosis mutation is a 57 kb deletion on human chromosome 17p13 that removes the majority of CTNS and the entire adjacent gene, CARKL/SHPK. OBJECTIVES In order to identify other gene...
BACKGROUND Cystinosis is a metabolic disease characterized by accumulation of cystine in different organs and tissues, leading to potentially life-threatening organ dysfunction. Infantile cystinosis typically leads to end-stage renal disease, necessitating renal replacement therapy. Liver disease in cystinosis is rare and is mostly reported as nodular regenerative hyperplasia leading to portal ...
Cystinosis is a rare autosomal recessive lysosomal storage disorder caused by mutations in the CTNS gene. Main dysfunction is a defective clearance of cystine from lysosomes that leads to accumulation of cystine crystals in every tissue of the body. There are three different forms: infantile nephropathic cystinosis, which is the most common form, juvenile nephropatic, and non-nephropathic cysti...
Children with infantile nephropathic cystinosis have evidence of visuospatial and arithmetic deficits on a background of normal intellectual and verbal skills. This study aimed to define further their behavioral phenotype. The Achenbach Child Behavior Checklist was completed by parents of: 64 children and adolescents with cystinosis (33 females, 31 males; mean age 8 y 8 mo, range 4 to 16y, SD 2...
Nephropathic cystinosis was first described in the early 1900s in a 21-mo-old boy who died of progressive anorexia; two siblings had previously died in infancy under similar circumstances (1). By meticulous observations and analyses, it became clear that abnormal cystine accumulation was characteristic of this autosomal recessive disease (2-4). Although some considered it to be a severe form of...
The goal of this work was to study white matter (WM) integrity in children with cystinosis, a rare lysosomal storage disorder resulting in cystine accumulation in peripheral and central nervous system tissue. Based on previous reports of cystine crystal formation in myelin precursors as well as evidence for specific cognitive deficits in visuospatial functioning, diffusion tensor imaging (DTI) ...
