Electropherograms showing PCR and double digestion of the PMP22 allele.
(A, B) PCR amplification products with the indicated primer pairs. 1: A-III1; 2: A-II3; 3: A-II4; 4: B-II3; 5: B-II4; 6: B-III1; 7: normal control; 8: CMT1A positive control. (C, D) PCR amplification products with the indicated primer pairs (the first three lanes of each half) and EcoRI and NsiI double digestion of the PCR products (the second three lanes of each half). 1: A-III1; 2: B-II3; 3: normal control; M: DNA marker.
CMT1: Charcot-Marie-Tooth disease myelin sheath type; PMP22: peripheral myelin protein 22.
