What is cystinuria?
Cystinuria is an inherited (genetic) disorder of the transport of an amino acid (a building block of protein) called cystine resulting in cystinuria (an excess of cystine in the urine) and the formation of cystine stones.

Cystinuria is an inherited defect of the renal tubules in which resorption of the amino acid cystine is impaired, urinary excretion is increased, and cystine stones form in the urinary tract.
Homocystinuria: A genetic disease due to an enzyme deficiency. Among other events, there is a buildup of the amino acid homocystine. Progressive mental retardation is common in untreated cases.

Homocystinuria is an inherited disorder in which the body is unable to process certain building blocks of proteins (amino acids) properly. The most common form of the condition is caused by the lack of an enzyme called cystathionine beta-synthase.
Homocystinuria is inherited in families as an autosomal recessive trait. This means that the child must inherit the defective gene from both parents to be seriously affected.

Cystinuria: High amounts of cystine are present in urine, and may not dissolve so it can be excreted. This leftover cystine can form stones.

Homocystinuria is a rare metabolic condition characterized by an excess of the compound homocystine in the urine.
Homocystinuria has several features in common with Marfan syndrome. Unlike Marfan syndrome, in which the joints tend to be "loose," in homocystinuria the joints tend to be "tight."

Homocystinuria: Homocystinuria is a rare metabolic condition where an amino acid, called homocystine, is found in abnormally high levels in the urine. It is an autosomal recessive trait.

Rare, inherited diseases such as renal tubular acidosis and cystinuria can increase your risk of kidney stones. So can more common disorders such as gout, chronic urinary tract infections, cystic kidney disease and hyperparathyroidism.
It occurs if you have the genetic disease called cystinuria. This disease results from a birth defect that causes the kidney to allow too much cystine into the urine. This type of stone formation is almost always diagnosed during childhood.
