Abstract

Cystinuria is an autosomal recessive disease manifested in the formation of kidney stones by a defect in renal reabsorption of cystine and other dibasic amino acids arginine, lysine and ornitina.Sua classification is based on molecular analysis and not the amino acid profile in urine disease type A, arising from mutations in the SLC3A1 gene; type B gene SLC7A9, AB type, due to mutations in both genes.Considerando that many studies on the sum of the rates of mutations in SLC3A1 and SLC7A9 not reach 100%, and due to the complex nature of renal transport of amino acids, the role of genes, and additional mutations in the etiology of cystinuria have been postulated. Additionally, the role of existing mutations already described differs according to the location of the population studied. Based on the above, the aim of our study consists in mapping genetic mutations in Brazilian families who have cystinuria and renal calculi in order to validate internally mutations described above and search for new ones that may be associated with this disease in our population.
