- Poor Feeding
Get Update Overview Molybdenum cofactor deficiency (MOCOD) is a rare autosomal recessive metabolic disorder characterized by onset in infancy of poor feeding, intractable seizures, and severe psychomotor retardation. [diseaseinfosearch.org]
Other systemic complications include abnormal respiratory drive, poor feeding that requires a gastrostomy tube, vomiting, gastroesophageal reflux, and aspiration pneumonia. Cho SY, Goh DL, Lau KC, Ong HT, Lam CW. [emedicine.medscape.com]
Poor weight gain / FTT Feeding therapy; gastrostomy tube placement may be required for concerns re aspiration &/or persistent feeding issues. [ncbi.nlm.nih.gov]
- Poor Growth
Poor growth may ensue. Affected individuals are at risk for severe psychomotor retardation, spasticity, and/or hypotonia. Most individuals have profound intellectual disability. [emedicine.medscape.com]

The observation that neither isolated xanthinuria nor a combined loss of xanthine dehydrogenase and aldehyde oxidase results in encephalopathy supports the conclusion that these effects result from the absence of sulfite oxidase activity. [ommbid.mhmedical.com]

Prognosis
Inform the family of the likely extremely poor neurologic prognosis if neonatal presentation of condition. [clinicaladvisor.com]
Prognosis for early-onset MoCD is poor, with about 75% succumbing in infancy to secondary complications of their neurologic disability (i.e., pneumonia). [ncbi.nlm.nih.gov]
Etiology
Rarely it is an etiology of psychomotor retardation of childhood. Lens dislocation outside of the neonatal period is a common finding but of variable onset. [clinicaladvisor.com]
Epidemiology
It has been observed in all ethnic groups but its rarity so far prevents clear delineation of epidemiologic patterns. [clinicaladvisor.com]

The diversity of reported semiologies suggests that seizures in those with typical MoCD are secondary to the diffuse cortical degeneration seen on ancillary brain imaging and not specific to the underlying pathophysiology. Developmental findings. [ncbi.nlm.nih.gov]

The deletion of fdhF (cg0618), annotated as formate dehydrogenase (FDH) and located in a cluster of genes conserved in the family Corynebacteriaceae, prevented formate utilization. [mic.microbiologyresearch.org]
