We report the postmortem findings of two infants and one child who died in Iraq. In each case, a specific clinical diagnosis was never established and all died at home. None of the cases had undergone newborn screening tests for inherited diseases.In case 1, a 3-day old neonate died without ever passing meconium. Autopsy revealed complete small intestinal obstruction due to meconium ileus. This was most likely due to cystic fibrosis. In case 2, a 6 month old boy died suddenly and unexpectedly after developing dehydration from vomiting. Autopsy revealed marked hepatomegaly with fatty infiltration that also involved the myocardium and kidney.
