Multiplex ligation-dependent probe amplification assay results. a The corresponding position of amplification products (number unit in bp) and α-globin gene cluster (NG_000006.1) sequence in the P140-C1 HBA kit (MRC-Holland). b The corresponding fragment ratio of MLPA results from the αα/αα, --SEA/αα and proband. X-axis is the product fragment length (bp), while Y-axis represents their ratios. According to the manufacturer’s instructions, probe ratios between 0.7 and 1.3 are defined as normal
