First Report of Compound Heterozygosity for Hb S (HBB : c.20A>T) and Hb Haringey (HBB: c.131A>G)

Sickle cell disease variants include hemoglobinopathies that result from inheritance of the sickle cell globin mutation with another globin mutation. The most common variants include the homozygous disease state (Hb SS disease), Hb S (HBB: c.20A>T)/Hb C (HBB: c.19G>A) disease and Hb S/β-thalassemia (Hb S/β-thal). Other rare/less common variants such as Hb S/Hb E (HBB: c.79G>A) and Hb S/HPFH [hereditary persistence of fetal hemoglobin (Hb)] disease exist. We report the first case of compound heterozygosity for Hb S and Hb Haringey (HBB: c.131A>G) in a 35-year-old male following a positive sickle screen test on hospital admission for pancreatitis. Ion exchange high performance liquid chromatography (HPLC), Hb electrophoresis and genetic sequencing were utilized to identify a new sickle Hb variant: Hb S/Hb Haringey. Hb S/Hb Haringey is a newly discovered sickle cell variant which seems to portray a mild/benign clinical phenotype of sickle cell disease.
