Molybdenum cofactor deficiency (MCD or MOCD) is a very rare, lethal, genetic condition caused by a loss of function of molybdenum-dependant enzymes, manifesting as severe and rapid neurological deterioration.On imaging it mimics hypoxic-ischaemic encephalopathy. The patient in the 1981 “American Journal of Clinical Nutrition” case report suffered from headaches, night blindness, and an accelerated heart and respiratory rate. Neurocognitive outcome is markedly improved and lifelong therapy is recommended.9 Molybdate therapy may benefit those with mutations in the GEPH gene.2 It is now possible to establish diagnosis in the prenatal period by mutational analysis or linkage studies in families where the specific genetic defect is known or by estimating sulfite oxidase in chorionic villus tissue.2 Prenatal diagnosis has the advantage of permitting decision regarding continuation of pregnancy and initiation of early treatment in the newborn child to arrest the illness.2. In 2009, Monash Children's Hospital at Southern Health in Melbourne, Australia reported that a patient known as Baby Z became the first person to be successfully treated for molybdenum cofactor deficiency type A.
