Introduction to Molybdenum Cofactor Deficiency
Molybdenum cofactor deficiency (MoCD) is a rare inherited metabolic disorder characterized by neonatal onset intractable seizures and severe neurological symptoms․
Molybdenum cofactor deficiency (MoCD) is a rare inherited metabolic disorder characterized by neonatal onset intractable seizures, severe psychomotor retardation, dysmorphic facies, and dislocated ocular lenses․ It represents a spectrum, with some individuals experiencing significant signs and symptoms in the neonatal period and early infancy (termed early-onset or severe MoCD) and others developing signs and symptoms in childhood or adulthood (termed late-onset or mild MoCD)․ Diagnosis often involves a characteristic biochemical profile allowing for early identification and treatment initiation․
Clinical Characteristics of Molybdenum Cofactor Deficiency
Children with early-onset or severe Molybdenum Cofactor Deficiency typically present with intractable seizures and severe neurological symptoms shortly after birth, while those with late-onset or mild MoCD may develop signs and symptoms later in childhood or adulthood․
Overview of Molybdenum Cofactor Deficiency
Molybdenum cofactor deficiency (MoCD) is an extremely rare autosomal recessive disorder that results in the combined deficiency of molybdenum-dependent enzymes․ It is characterized by severe and progressive neurologic deterioration in early infancy, with less than 150 reported cases in the literature․ The absence of the molybdenum cofactor leads to the accumulation of toxic levels of sulphite٫ resulting in severe neuronal loss٫ reactive astrogliosis٫ and spongiosis․
Spectrum of Symptoms
Molybdenum cofactor deficiency presents a spectrum of symptoms, from severe intractable seizures and psychomotor retardation in early infancy to milder symptoms in childhood or adulthood․
Genetic Mutations Leading to the Deficiency
Molybdenum cofactor deficiency is caused by mutations in genes involved in molybdenum cofactor biosynthesis, such as MOCS1, MOCS2, MOCS3, and GEPH, which result in the combined deficiency of molybdenum-dependent enzymes, leading to severe neurological impairment․
Diagnosis and Treatment of Molybdenum Cofactor Deficiency
Early diagnosis of Molybdenum Cofactor Deficiency is crucial to start novel therapies that may improve outcomes for affected individuals․
