Anemia, sideroblastic, 5

Summary

Sideroblastic anemia-5 (SIDBA5) is an autosomal recessive hematologic disorder characterized by abnormal iron accumulation in the mitochondria or erythroid cells. The pathologic iron deposits appear to ring the nucleus, resulting in a 'ringed sideroblast' on pathologic examination. Affected individuals have congenital hypochromic microcytic anemia apparent in childhood; they may also develop thrombocytopenia or pancytopenia (summary by Crispin et al., 2020). For a discussion of genetic heterogeneity of sideroblastic anemia, see SIDBA1 (300751). [from OMIM]
