Disease ID | Source | Name | Description |
219800 | OMIM | Cystinosis, nephropathic type (CTNS) | A form of cystinosis, a lysosomal storage disease due to defective transport of cystine across the lysosomal membrane. This results in cystine accumulation and crystallization in the cells causing widespread tissue damage. The classical nephropathic form has onset in the first year of life and is characterized by a polyuro-polydipsic syndrome, marked height-weight growth delay, generalized impaired proximal tubular reabsorptive capacity, with severe fluid-electrolyte balance alterations, renal failure, ocular symptoms and other systemic complications. The disease is caused by variants affecting the gene represented in this entry. |
219750 | OMIM | Cystinosis, adult, non-nephropathic type (CTNSANN) | A form of cystinosis, a lysosomal storage disease due to defective transport of cystine across the lysosomal membrane. This results in cystine accumulation and crystallization in the cells causing widespread tissue damage. Cystinosis adult non-nephropathic type is characterized by ocular features and a benign course. Patients manifest mild photophobia due to conjunctival and corneal cystine crystals. The disease is caused by variants affecting the gene represented in this entry. |
219900 | OMIM | Cystinosis, late-onset juvenile or adolescent nephropathic type (CTNSJAN) | A form of cystinosis, a lysosomal storage disease due to defective transport of cystine across the lysosomal membrane. This results in cystine accumulation and crystallization in the cells causing widespread tissue damage. Late-onset juvenile or adolescent nephropathic cystinosis is an intermediated form, manifesting first at age 10 to 12 years with proteinuria due to glomerular damage rather than with the manifestations of tubular damage that occur first in infantile cystinosis. There is no excess amino aciduria and stature is normal. Photophobia, late development of pigmentary retinopathy, and chronic headaches are features. The disease is caused by variants affecting the gene represented in this entry. |
