Summaries for Anemia, Congenital Dyserythropoietic, Type Ib

OMIM : 57 Congenital dyserythropoietic anemia type I is an autosomal recessive hematologic disorder characterized by congenital macrocytic anemia secondary to ineffective erythropoiesis. The bone marrow shows erythroid hyperplasia, with nuclear abnormalities in most erythroblasts. Up to 3% of erythroblasts have interchromatin bridges, and erythroblast nuclei are abnormally electron dense with spongy ('Swiss cheese-like') heterochromatin on electron microscopy. Some reported patients have distal digital abnormalities (summary by Ahmed et al., 2006). For a general phenotypic description and a discussion of genetic heterogeneity of CDA, see CDAN1A (224120). (615631)

MalaCards based summary : Anemia, Congenital Dyserythropoietic, Type Ib, is also known as cdan1b, and has symptoms including icterus An important gene associated with Anemia, Congenital Dyserythropoietic, Type Ib is C15orf41 (Chromosome 15 Open Reading Frame 41). Affiliated tissues include bone, bone marrow and liver, and related phenotypes are splenomegaly and hepatomegaly

UniProtKB/Swiss-Prot : 75 Anemia, congenital dyserythropoietic, 1B: An autosomal recessive blood disorder characterized by morphological abnormalities of erythroblasts, ineffective erythropoiesis, macrocytic anemia and secondary hemochromatosis. It is occasionally associated with bone abnormalities, especially of the hands and feet (acrodysostosis), nail hypoplasia, and scoliosis. Ultrastructural features include internuclear chromatin bridges connecting some nearly completely separated erythroblasts and an abnormal appearance (spongy or Swiss-cheese appearance) of the heterochromatin in a high proportion of the erythroblasts.
