Introduction: Nephropathic cystinosis is a rare genetic disorder characterized by cystine accumulation in lysosomes that causes early renal dysfunction and progressive chronic kidney disease. Although several metabolic pathways, including oxidative stress and inflammation, have been implicated in the progression of renal parenchyma damage, the precise mechanisms driving its progression are not fully understood. Recent studies suggest that epigenetic modifications, particularly DNA methylation (DNAm), play a critical role in the development of chronic kidney disease.

Cystinosis is a autosomal recessive lysosomal storage disorder caused by mutations in the CTNS gene, which encodes cystinosin, a cystine transporter. The defective function of cystinosin leads to cystine accumulation in the lysosome, resulting in progressive multi-organ damage. Cystinosis manifests early in life, with nephropathic cystinosis typically presenting in infancy with renal Fanconi syndrome, leading to chronic kidney disease and end-stage renal disease if untreated.

Throughout their lifetime, patients with CKD experience evolving dietary needs, influenced by their age and the progression of the disease. A patient-centered approach is vital. In childhood, adequate nutrition is vital for managing CKD and supporting growth and development, especially for growth spurts during adolescence.

Background: Cystinosis is a rare autosomal recessive lysosomal storage disorder caused by mutations in the CTNS gene, which encodes cystinosin, a lysosomal cystine transporter. These mutations disrupt cystine efflux, leading to its accumulation in lysosomes and subsequent cellular damage. While more than 140 mutations have been identified, the functional and structural impacts of many nonsynonymous single nucleotide polymorphisms (nsSNPs) remain poorly understood.
