Congenital Erythropoietic Porphyria

📋Overview

This condition, also known as Günther disease, results from a genetic mutation that leads to the systemic accumulation of porphyrins. Because these compounds react to light, their presence in the skin and tissues can cause cellular damage following environmental exposure.

The disorder is classified among the porphyrias, a group of metabolic diseases involving enzymatic defects in the heme biosynthesis pathway. In this specific form, the deficiency of uroporphyrinogen III synthase typically results in an overproduction of porphyrins that impact the bone marrow and other organs.
