The DQ values indicative of the 17a–17b deletion pattern are underlined. | ||||
From our study, values of the DQ were within the range 0.75–1.31 (mean 0.95) for normal control samples, 0.38–0.64 (mean 0.48) for a heterozygous deletion control, and 1.40–1.79 (mean 1.55) for a heterozygous duplication control. They were concordant with those obtained by Yau et al.20 | ||||
As an example (indicated in bold characters), the DQ for CFTR exon 17a compared to DSCR1 exon 4 is DQ17a/DSCR1 = Patient (CFTR 17a/DSCR1)/Control (CFTR 17a/DSCR1) = (827/565)/(1292/461) = 0.52. | ||||
