The nine DSVs include one novel deletion DSV, five SNPs and three novel heterozygous DSVs. For deletion DSV (g.38901027_30delTAAA) and deletion SNP [g.38901007delT (rs10713585)], top panel shows wild type, middle panel heterozygous and bottom panel cloning DNA sequence. The deletions are underlined and labeled. For SNP [g.38900291C>G (rs2053071)], top panel shows wild type, middle panel heterozygous and bottom panel homozygous DNA sequence. For SNP g.38900907A>G (rs4803006), top panel shows wild type and bottom panel homozygous DNA sequence. For other novel heterozygous DSVs (g.38900748T>A, g.38899903T>C and g.38899781C>G), and SNPs [g.38900145C>T (rs116900177) and g.38899968A>G (rs112492606)], top panels show wild type and bottom panels heterozygous DNA sequences, which are marked with arrows.
