<unk>  anemia may be classified according to its etiology into two groups, congenital and acquired. Congenital catagory include X-linked, autosomal and mitochondrialDNA defects. Acquired<unk>  anemias is divided in to 2 catogries, acquired reversible and acquired clonal.<unk>  anemias secondry to alcohol ingestion,drugs like isoniazid and chloramphenicol, comes under the catagory of acquired reversible<unk>  anemia. Copper and vitamin B6 deficiency also causes acquired reversible<unk>  anemias. Acquired clonal<unk>  anemias include refractory anaemia with ring sideroblasts (RARS) refractory anaemia with multilineage dysplasia and ring sideroblasts (RCMD) and refractory anaemia with ring sideroblasts and thrombocytosis (RARS-T).<unk>  anemia can be divided according to MCV mean corpuscular volume in to two catogries, MCV decreased and MCV normal or increased. X linked<unk>  anemia in males, X linked<unk>  anemia with ataxia, and autosomal recessive congenital<unk>  anemia (ARCSA) present with low MCV. Isoniazid also causes low MCV. Alcoholism, copper defeciency, X linked<unk>  anemia in females and pearson marrow-pancreas syndrome will show either high or normal MCV.
