Which one of the following is a genetic disorder of kidneys?
Options:
Answer:
Solution:
Cystinuria is an autosomal recessive genetic disorder that affects the amino acid transport in the kidneys and intestine. It leads to a defective reabsorption of cystine and other dibasic amino acids in the proximal convoluted tubule of the kidneys. This results in an excess of cystine in the urine, which can precipitate and form cystine stones in the kidneys, ureter, and bladder.
Calcium stones are typically caused by dietary factors, metabolic issues, or hyperparathyroidism.
Struvite stones are usually formed in response to an infection in the urinary tract.
Uric acid stones are often associated with a high purine diet, gout, or conditions that cause rapid cell turnover.
Answer: Cystine stones.
