mye-eh-lo-dis-plas-tik sin-drome) disease in which the bone marrow does not function normally.

A clonal hematopoietic disorder characterized by dysplasia and ineffective hematopoiesis in one or more of the hematopoietic cell lines. The dysplasia may be accompanied by an increase in myeloblasts, but the number is less than 20%, which, according to the who guidelines, is the requisite threshold for the diagnosis of acute myeloid leukemia. It may occur de novo or as a result of exposure to alkylating agents and/or radiotherapy. who, 2001)

A disorder characterized by insufficiently healthy hematapoietic cell production by the bone marrow.

A group of diseases in which the bone marrow does not make enough healthy blood cells.

Clonal hematopoietic stem cell disorders characterized by dysplasia in one or more hematopoietic cell lineages. They predominantly affect patients over 60, are considered preleukemic conditions, and have high probability of transformation into acute myeloid leukemia.

Your bone marrow is the spongy tissue inside some of your bones, such as your hip and thigh bones. It contains immature cells, called stem cells. The stem cells can develop into the red blood cells that carry oxygen through your body, the white blood cells that fight infections, and the platelets that help with blood clotting. If you have a myelodysplastic syndrome, the stem cells do not mature into healthy blood cells. This leaves less room for healthy cells, which can lead to infection, anemia, or easy bleeding.myelodysplastic syndromes often do not cause early symptoms and are sometimes found during a routine blood test. If you have symptoms, they may include
