Fourteen pedigrees included affected and unaffected infants, and a single pedigree had all 4 infants affected by the condition born to consanguineous but otherwise healthy parents. You inherit one HFE gene from each of your parents. Four pedigrees had clear evidence of neonatal hemochromatosis associated with maternal infection, including coxsackievirus, E.

Whitington postulated that some cases of neonatal hemochromatosis result from maternal alloimmunity directed at the fetal liver, and therefore do not represent an inherited mendelian disorder.
