Congenital dyserythropoietic anemia type IV (CDA IV) is a newly discovered form of CDA (see this term) characterized by ineffective erythropoiesis and hemolysis that leads to severe anemia at birth.

Hereditary orotic aciduria is an extremely rare (less than 20 cases identified worldwide) autosomal recessive disorder characterized by retarded growth, anemia and excessive urinary excretion of orotic acid. It is due to a severe deficiency in the activity of the pyrimidine pathway enzyme uridine 5'-monophosphate (UMP) synthase (bifunctional enzyme containing two activities: orotate phosphoribosyltransferase and orotidine 5'-monophosphate decarboxylase), coded by a single gene (UMPS) localized to chromosome 3q13.

Poikiloderma with neutropenia is a rare, genetic hereditary poikiloderma disorder characterized by early-onset poikiloderma (which typically begins in the extremities, progresses centripetally and eventually involves the trunk, face and ears) associated with chronic neutropenia, recurrent infections, pachyonychia and palmoplantar keratoderma. Growth and/or develomental delay and hepato- and/or splenomegaly are additional reported features.

Sialuria is an extremely rare metabolic disorder described in fewer than 10 patients to date and characterized by variable signs and symptoms, mostly in infancy, including transient failure to thrive, slightly prolonged neonatal jaundice, equivocal or mild hepatomegaly, microcytic anemia, frequent upper respiratory infections, gastroenteritis, dehydration and flat and coarse facies. Learning difficulties and seizures may occur in childhood.

Sanfilippo syndrome comprises several forms of lysosomal storage diseases due to impaired degradation of heparan sulfate. The deficient enzyme in Sanfilippo syndrome C, or MPS IIIC, is an acetyltransferase that catalyzes the conversion of alpha-glucosaminide residues to N-acetylglucosaminide in the presence of acetyl-CoA.For a general phenotypic description and a discussion of genetic heterogeneity of Sanfilippo syndrome, see MPS IIIA (OMIM ).

ALG1-CDG is a severe form of congenital disorders of N-linked glycosylation characterized by severe developmental and psychomotor delay, muscular hypotonia, intractable early-onset seizures, and microcephaly. Additional features include altered blood coagulation with a high probability of hemorrhages or thromboses, nephrotic syndrome, ascites, hepatomegaly, cardiomyopathy, ocular manifestations (strabismus, nystagmus), and immunodeficiency. The disease is caused by loss-of-function mutations in the gene ALG1 (16p13.3).
