Myelodysplastic syndrome associated with isolated del(5q)
The 5q- syndrome is a myelodysplastic syndrome characterized by a defect in erythroid differentiation. Patients have severe macrocytic anemia, normal or elevated platelet counts, normal or reduced neutrophil counts, erythroid hypoplasia in the bone marrow, and hypolobated micromegakaryocytes (Ebert et al., 2008). [from OMIM]
Myelodysplastic syndrome
Myelodysplastic syndrome (MDS) is a heterogeneous group of clonal hematologic stem cell disorders characterized by ineffective hematopoiesis resulting in low blood counts, most commonly anemia, and a risk of progression to acute myeloid leukemia (AML; 601626). Blood smears and bone marrow biopsies show dysplastic changes in myeloid cells, with abnormal proliferation and differentiation of 1 or more lineages (erythroid, myeloid, megakaryocytic). MDS can be subdivided into several categories based on morphologic characteristics, such as low-grade refractory anemia (RA) or high-grade refractory anemia with excess blasts (RAEB). Bone marrow biopsies of some patients show ringed sideroblasts (RARS), which reflects abnormal iron staining in mitochondria surrounding the nucleus of erythrocyte progenitors (summary by Delhommeau et al., 2009 and Papaemmanuil et al., 2011).

Pancytopenia
An abnormal reduction in numbers of all blood cell types (red blood cells, white blood cells, and platelets). [from HPO]
Myelodysplasia
Clonal hematopoietic stem cell disorders characterized by dysplasia (ineffective production) in one or more hematopoietic cell lineages, leading to anemia and cytopenia. [from HPO]
Inherited bone marrow failure syndrome
A group of inherited genetic hematopoietic stem cell disorders characterized by bone marrow failure that involves one or more cell lines. Representative examples include Fanconi anemia, Diamond-Blackfan anemia, and Shwachman-Diamond syndrome. [from NCI]
Bone marrow failure syndrome
A familial or acquired bone marrow failure syndrome. [from NCI]
Hypoplastic anemia
Anemia with varying degrees of erythrocytic hypoplasia without leukopenia or thrombocytopenia. [from HPO]
Pure red-cell aplasia
A type of anemia resulting from suppression of erythropoiesis with little or no abnormality of leukocyte or platelet production. Erythroblasts are virtually absent in bone marrow; however, leukocyte and platelet production show little or no reduction. [from HPO]
Diamond-Blackfan anemia
Diamond-Blackfan anemia (DBA) is characterized by a profound normochromic and usually macrocytic anemia with normal leukocytes and platelets, congenital malformations in up to 50%, and growth deficiency in 30% of affected individuals. The hematologic complications occur in 90% of affected individuals during the first year of life. The phenotypic spectrum ranges from a mild form (e.g., mild anemia or no anemia with only subtle erythroid abnormalities, physical malformations without anemia) to a severe form of fetal anemia resulting in nonimmune hydrops fetalis. DBA is associated with an increased risk for acute myelogenous leukemia (AML), myelodysplastic syndrome (MDS), and solid tumors including osteogenic sarcoma. [from GeneReviews]
