Question

Quizplus · Accepted Answer

Isovaleric acidemia is a rare genetic disorder that affects the breakdown of certain amino acids. A symptom of this condition is the characteristic odor of "sweaty feet" in urine, as well as a positive ketone test. Cystinuria is a condition where cystine (an amino acid) builds up in the urine and can lead to kidney stones, but it does not typically cause a "sweaty feet" odor. Alkaptonuria is another rare genetic condition that causes urine to turn dark when exposed to air, but it is not associated with a "sweaty feet" odor. Tyrosyluria is a very rare genetic disorder that affects the breakdown of the amino acid tyrosine, but it also does not typically cause a "sweaty feet" odor.
