Padlock probes detect single nucleotide variations in genomic DNA. Two padlock probes generated by PCR, WD14wt and WD14mut, were ligated in the presence of genomic DNA from individuals homozygous for the wild-type sequence of the ATP7B gene or for the mutant variant (C3207A) and the amplification products were examined by agarose gel electrophoresis.
