These deficiencies allow heme precursors to accumulate, causing toxicity. Porphyrias are defined by the specific enzyme deficiency.

In animal reproduction studies with chloroquine, accumulation in fetal ocular tissues was observed and remained for several months following drug elimination from the rest of the body. Anuric individuals can be readily diagnosed by assaying a plasma or serum specimen for the characteristic elevated levels of polycarboxylated porphyrins. Quantitative plasma porphyrin levels are often much higher than those of patients with normal renal function, who excrete large amounts of these water-soluble porphyrins in urine.
