Semi-quantitative PCR analysis of the markers at the proximal and distal breakpoint region of 22q11. Genetic markers D22S1138 (A) and SHGC-145314 (B) were used against control marker CF (cystic fibrosis). The result showed a control-to-patient intensity ratio of 2:1 and 1:1 respectively. N means normal control and P means patient.
