Agarose gel electrophoresis showing deletional high persistence of foetal hemoglobin (HPFH-3). Amplifaction of 841 bp PCR product is for normal and 607 bp for deletional HPFH-3. Lane A1, A2, A3 and A4 are normal and Lane A5 A6, A7 and A8 are heterozygous for HPFH-3, lane L1 and L2 are 500bp and 100 bp DNA ladder
