Open AccessIntegrated multi-omics reveals anaplerotic rewiring in methylmalonyl-CoA mutase deficiency
Methylmalonic aciduria (MMA) is an inborn error of metabolism with multiple monogenic causes and a poorly understood pathogenesis, leading to the absence of effective causal treatments. Here we employ multi-la...

Open AccessSpectrum and characterization of bi-allelic variants in MMAB causing cblB-type methylmalonic aciduria
Pathogenic variants in MMAB cause cblB-type methylmalonic aciduria, an autosomal-recessive disorder of propionate metabolism. MMAB encodes ATP:cobalamin adenosyltransferase, using ATP and cob(I)alamin to create 5...

Open AccessEpimutations in both the TESK2 and MMACHC promoters in the Epi-cblC inherited disorder of intracellular metabolism of vitamin B12
epi-cblC is a recently discovered inherited disorder of intracellular vitamin B12 metabolism associating hematological, neurological, and cardiometabolic outcomes. It is produced by an epimutation at the promoter...

Open AccessKey patient-reported outcomes in children and adolescents with intoxication-type inborn errors of metabolism: an international Delphi-based consensus
Acute intoxication-type inborn errors of metabolism (IT-IEM) such as urea cycle disorders and non-acute IT-IEM such as phenylketonuria (PKU) and their treatment have a major impact on the life of affected chil...

Chapter
Biotin-Responsive Disorders
Two inherited defects affecting the coenzyme function of biotin are known: holocarboxylase synthetase (HCS) deficiency and biotinidase deficiency. Both lead to deficiency of all biotin-dependent carboxylases, ...

Disorders of Cobalamin Metabolism
Vitamin B12 (Cbl) is needed for just two metabolic reactions in man, the methylation of homocysteine to methionine (cofactor methyl-Cbl) and the conversion of methylmalonyl-CoA to succinyl-CoA (cofactor adenosyl-...

Disorders of Ornithine and Proline Metabolism
Hyperornithinaemia due to ornithine aminotransferase (OAT) deficiency results from loss of function mutations in OAT and causes gyrate atrophy of the choroid and retina (GA), a progressive retinal degeneration. T...

Open AccessThe biochemical subtype is a predictor for cognitive function in glutaric aciduria type 1: a national prospective follow-up study
The aim of the study was a systematic evaluation of cognitive development in individuals with glutaric aciduria type 1 (GA1), a rare neurometabolic disorder, identified by newborn screening in Germany. This na...

Open AccessReducing complexity: explaining inborn errors of metabolism and their treatment to children and adolescents
Inborn errors of metabolism (IEM) are a group of rare, heterogeneous and complex genetic conditions. Clinically, IEM often affect the central nervous system and other organs. Some carry the risk of progression...
