Figure 2: DNA sequencing result for the mother’s sample showing a small deletion of 25bp at position (i) NG_000007.3:g. 70795_70819del (HBB:c.93-23_94del) or (ii) NG_000007.3:g. 70794_70818del (HBB:c.93-22_95del). This ambiguity is due to the presence of “T’ base at both 5’and 3’breakpoint of the deletion [8]. The same deletion was found in the proband’s sample.
