Hereditary spherocytosis with high fetal hemoglobin: an interesting case.

abstract：:Anti-Lepore hemoglobins (Hbs) are rare βδ fusion variants that arise from non homologous crossover during meiosis. We describe the application of multiplex ligation-dependent probe amplification (MLPA) to test for a suspected anti-Lepore Hb in an individual with an ambiguous Hb variant detected on routine screening by...
