Comments: Found in a heterozygote 3-years old boy with hemolytic anaemia since birth, elevated levels of HbF and HbA2 and target cells in the blood smear. The 12bp in frame deletion leading to a deletion of four amino acids. Patient also carries a mutation in PIEZO1 (c.5195C>T). Whether the clinical picture of the patient is caused by a strong modifying effect of the new mutation in PIEZO1 or is combined effect of two strongly deleterious mutations of PIEZO1 and β-globin gene is unclear.

We follow the HGVS sequence variant nomenclature and IUPAC standards.
