Kidney Int ; suppl Adenosylcobalamin AdoCbl — the coenzyme for methylmalonyl-CoA mutase enzyme.

Adolescent and adult presentation. The biochemical hallmark is moderate homocystinuria with low to normal plasma methionine levels.

The C-terminus is thought to guide vitamin B 12 to methionine synthase [ Plesa et al ]. Individuals with the distinctive laboratory findings of a specific disorder of intracellular cobalamin metabolism described in Suggestive Findings are likely to be diagnosed using gene -targeted testing see Option 1whereas symptomatic individuals with nonspecific supportive clinical and laboratory findings in whom the diagnosis of a disorder of intracellular cobalamin metabolism has not been considered are more likely to be diagnosed using comprehensive genomic testing see Option 2.

Most reported variants have been nonconservative missense variants. Only five individuals with cblJ have been reported.

The identification of disorders of intracellular cobalamin metabolism relies on the following testing Table To establish the diagnosis of vitamin B 12 deficiency, it is necessary to measure serum vitamin B 12 concentrations in both affected newborns and their mothers.

Gailus et al []Alfadhel et al []. Abetalipoproteinemia Apolipoprotein B deficiency Chylomicron retention disease. Gene identification for the cblD defect of vitamin B12 metabolism. If the pathogenic variant s have not been identified in an affected family member, prenatal testing for pregnancies at risk for a disorder of intracellular cobalamin metabolism may be possible using these methods: Freeman and Company, Plasma acylcarnitine analysis to detect elevation of propionylcarnitine C3 or confirm the elevated propionylcarnitine following newborn screening.

Features of this autosomal recessive disorder may include poor cobalamin absorption, abnormal renal tubular protein reabsorption, and urinary tract malformations. Some expected metabolite abnormalities were mild enough to be difficult to detect. Altogether five different DNA variants accounted for 22 of 24 observed pathogenic variants. In a family with more than one affected individual, the mother of an affected male is an obligate heterozygote carrier.

Disorders causing both methylmalonic acidemia and homocystinuria Vitamin B 12 deficiency.

Because it is likely that testing methodology and our understanding of genes, allelic variants, and diseases will improve in the future, consideration should be given to banking DNA of affected individuals.

More than 90 variants have been identified in persons with cblC. Vitamin B12 administration by subcutaneous catheter device in a cobalamin A cblA patient. Rarely, hemolytic uremic syndrome and obtundation. The following disorders may cause clinical manifestations and laboratory abnormalities similar to those seen in disorders of intracellular cobalamin metabolism. Infants are usually started at a daily dose of 1. Early onset methylmalonic aciduria and homocystinuria cblC type with demyelinating neuropathy.

J Inher Metab Dis, Variants listed in the table have been provided by the authors. Individuals with cblF often present during infancy with symptoms similar to cblC — IUGR, poor postnatal growth, feeding difficulties, and developmental delay — but can also have stomatitis with or without glossitis and congenital heart malformations [ Alfadhel et al ].
