Comments: Found in a newborn Greek female who received erythrocyte transfusion immediately after birth due to severe hemolytic anaemia. Mother and maternal grandmother of the proband had a history of unexplained neonatal anemia restricted to neonatal and early infant period, microcytic hypochromic hemolytic anemia and cholelithiasis later in life. The deletion caused severe but transient neonatal anemia and a non-transfusion-dependent chronic hemolytic anemia state later in life, resembling mild β-thalassemia intermedia. The Greek deletion is about 72 kb in length, spanning from hypersensitive site 4 (HS4) in the LCR to the 3’ end of the β-globin gene.

We follow the HGVS sequence variant nomenclature and IUPAC standards.
