Abstract
We described the clinical and biochemical findings in a 32 day-old boy with the Dubin-Johnson syndrome. Only two other patients diagnosed as having the Dubin-Johnson syndrome during neonatal period have been reported in the literature.
The ratio of urinary coproporphyrin isomer I of our patient was 97% and that of his parents were carrier level, confirming that increased urinary excretion of coproporphyrin isomer I is of diagnostic value in neonates with the Dubin-Johnson syndrome.
