A characteristic biochemical profile … Molybdenum cofactor deficiency is a rare human disease in which the absence of molybdopterin – and consequently its molybdenum complex, commonly called molybdenum cofactor – leads to accumulation of toxic levels of sulphite and neurological damage. Molybdenum cofactor deficiency (MOCD) is considered a rare but not extremely rare disorder (on the order of 100-200 patients reported worldwide). Definition. 5 references maximum.

The most common mutation observed is in the MOCS1 gene, followed by the MOCS2 gene . In molybdenum deficiency, activities of these 3 enzymes decrease. ), National Institute of Mental Health and Neurosciences (NIMHANS), Bangalore, India. These enzymes help break down (metabolize) different substances in the body, some of which are toxic if not metabolized. Reference 1 must be the article on which you are commenting. Four genes (MOCS1, MOCS2, MOCS3, and GEPH) are needed for the production pathway of molybdenum cofactor.
