BACKGROUND Cystinosis is an autosomal recessive disorder, caused by mutations of the lysosomal cystine carrier cystinosin, encoded by the CTNS gene (17p13). The concomitant intralysosomal cystine accumulation leads to multi-organ damage, with kidneys being the first affected. Altered mitochondrial oxidative phosphorylation has been demonstrated in animal proximal tubules loaded with cystine dim...

BACKGROUND Cystinosis is a rare autosomal recessive disease, caused by intracellular cystine accumulation due to a defect in the lysosomal cystine carrier. Treatment with cysteamine favours the transport of cystine out of the lysosomes, diminishes organ damage, and postpones the progression of renal failure. The extra-renal deposition of cystine continues after renal transplantation, leading to...

Cystinosis is an autosomal recessive metabolic disease that belongs to the family of lysosomal storage disorders (LSDs). The defective gene is CTNS encoding the lysosomal cystine transporter, cystinosin. Cystine accumulates in all tissues and leads to organ damage including end-stage renal disease. Using the Ctns(-/-) murine model for cystinosis, we tested the use of hematopoietic stem and prog...

INTRODUCTION Infantile nephropathic cystinosis (INC) is a metabolic disorder due to impaired carrier-mediated transport of cystine out of cellular lysosomes. OBJECTIVE To examine the prevalence and clinical characteristics of INC in paediatric patients with endstage renal disease (ESRD) in Serbia and give a recent statement of the disease. METHODS ESRD database of the Centre for Paediatric ...

Cystinosis is a rare autosomal recessive disorder characterized by the intralysosomal accumulation of cystine in all tissues due to mutations in the CTNS gene (17p13.3). Infantile nephropatic cystinosis is the most severe and the most frequent form of the disease. It causes renal Fanconi syndrome, leading to end stage renal failure around the age of 10 years if left untreated. Cystine accumulat...

Cystinosis is a rare autosomal recessive disorder characterized by lysosomal cystine accumulation due to loss of function of the lysosomal cystine transporter (CTNS). The most common mutation in cystinosis patients of Northern Europe consists of a 57-kb deletion. This deletion not only inactivates the CTNS gene but also extends into the non-coding region upstream of the start codon of the TRPV1...

In nephropathic cystinosis, corneal cystine crystals cause severe photophobia and corneal erosions. Topical cysteamine dissolves these crystals, but cannot be marketed because it rapidly oxidizes to the disulfide form, cystamine, at room temperature. Since cystamine itself could be used commercially, we compared the efficacy of cystamine and cysteamine with respect to cystine crystal dissolutio...

One of the founders of the field of inborn errors of metabolism, J. Edwin Seegmiller, once said, “Cystinosis is a durable, but perhaps not doable, problem.” Since he said that more than 50 years ago, great progress has been made in understanding this complex multiorgan, systemic disease. Now with genotyping readily available, a host of new questions can be asked, such as, why are some late comp...

Cystinosis is a rare autosomal recessive storage disorder characterized by defective lysosomal efflux of cystine due to mutations in the CTNS gene encoding the lysosomal cystine transporter, cystinosin. Lysosomal cystine accumulation leads to crystal formation and functional impairment of multiple organs. Moreover, cystinosis is the most common inherited cause of renal Fanconi syndrome in child...

BACKGROUND AND OBJECTIVES Cystinosis is an autosomal recessive disease characterized by the intralysosomal accumulation of cystine, as a result of a defect in cystine transport across the lysosomal membrane. Three clinical forms have been described on the basis of severity of symptoms and age of onset: infantile cystinosis, characterized by renal proximal tubulopathy and progression to end-stag...
