Description : Cystinuria is an autosomal disorder characterized by impaired epithelial cell transport
of cystine and dibasic amino acids (lysine, ornithine, and arginine) in the proximal
renal tubule and gastrointestinal tract. The impaired renal reabsorption of cystine
and its low solubility causes the formation of calculi in the urinary tract, resulting
in obstructive uropathy, pyelonephritis, and, rarely, renal failure (summary by Barbosa
et al., 2012).;
Inheritance : Autosomal dominant; Autosomal recessive;
Molecular basis : Caused by mutation in the solute carrier family 3 (cystine, dibasic, and neutral amino
acid transporter), member 1 gene (SLC3A1, 104614.0001); Caused by mutation in the solute carrier family 7 (cationic amino acid transporter,
y system), member 9 gene (SLC7A9, 604144.0001);
Laboratory abnormalities : Increased urinary excretion of cystine; Increase urinary excretion of lysine, arginine, and ornithine;
