Application of multiplex ligation-dependent probe amplification to screen for β-globin cluster deletions: detection of two novel deletions in a multi ethnic population.

Abstract excerpt

Hereditary persistence of fetal hemoglobin (HPFH) and δβ-thalassemia (δβ-thal) are heterogeneous disorders caused by deletions within the β-globin gene cluster. When combined with other β-thal mutations or structural hemoglobin (Hb) variants, these deletions give rise to clinical phenotypes ranging from an asymptomatic condition to β-thal major (β-TM). Overlap in hematological parameters and variability in...
