<unk>  is a rare human disease in which the absence of molybdopterin – and consequently its<unk>  complex, commonly called<unk><unk>  – leads to accumulation of toxic levels of sulphite and neurological damage. Usually this leads to death within months of birth, due to the lack of active sulfite oxidase. Furthermore, a mutational block in<unk><unk>  biosynthesis causes absence of enzyme activity of xanthine dehydrogenase/oxidase and aldehyde oxidase.
