Anemia, and Vomiting

Vitamin B12-unresponsive methylmalonic acidemia type mut0 is an inborn error of metabolism characterized by recurrent ketoacidotic comas or transient vomiting, dehydration, hypotonia and intellectual deficit, which does not respond to administration of vitamin B12.

Interstitial lung and liver disease is an autosomal recessive disorder characterized by onset of respiratory insufficiency and progressive liver disease in infancy or early childhood. Pathologic examination of lung lavage is consistent with pulmonary alveolar proteinosis (summary by Hadchouel et al., 2015).

Complement hyperactivation, angiopathic thrombosis, and protein-losing enteropathy is characterized by abdominal pain and diarrhea, primary intestinal lymphangiectasia, hypoproteinemic edema, and malabsorption. Some patients also exhibit bowel inflammation, recurrent infections associated with hypogammaglobulinemia, and/or angiopathic thromboembolic disease. Patient T lymphocytes show increased complement activation, causing surface deposition of complement and generating soluble C5a (Ozen et al., 2017).

Methylmalonic aciduria is a genetically heterogeneous disorder of methylmalonate and cobalamin (cbl; vitamin B12) metabolism. Different forms of isolated methylmalonic aciduria have been classified according to complementation groups of cells in vitro. Patients with defects in the synthesis of AdoCbl are usually responsive to vitamin B12 therapy and are classified as 'cbl' type: these include cblA and cblB (OMIM ), which is caused by mutation in the MMAB gene (OMIM ) on 12q24. See also cblH (OMIM ), which may be a subset of cblA. The 'mut' form of MMA (OMIM ) is caused by mutation in the MUT gene on chromosome 6p. In general, the mut form of MMA is unresponsive to vitamin B12 therapy.Combined methylmalonic aciduria and homocystinuria may be seen in complementation groups cblC (OMIM ), cblD (OMIM ), cblF (OMIM ), and cblJ (OMIM ).

Isobutyryl-CoA dehydrogenase deficiency is an inborn error of valine metabolism. The prevalence is unknown. Only one symptomatic patient (with anaemia, failure to thrive, dilated cardiomyopathy and plasma carnitine deficiency) has been described so far, but several series of patients have been identified through newborn screening programs relying on detection of increased C(4)-carnitine levels by tandem mass spectrometry. The disorder is caused by mutations in the ACAD8 gene (11q25).

Autoinflammation with infantile enterocolitis is an autosomal dominant disorder characterized by onset of recurrent flares of autoinflammation in early infancy. Affected individuals tend to have poor overall growth and gastrointestinal symptoms in infancy associated with laboratory evidence of activated inflammation. This initial presentation is followed by recurrent febrile episodes with splenomegaly and sometimes hematologic disturbances, arthralgias, or myalgias. The disorder results from overactivation of an arm of the immune response system (Romberg et al., 2014; Canna et al., 2014).
