Electropherogram of direct sequencing (a) Mother’s nail sample. (b) 2nd-born child. The forward and reverse read show two peaks at the nucleotide position 588 of HBs antigen in both the nails and serum. A: In the forward read, the large peak indicates “C” (G145A) and the small peak indicates “G” (wild-type) in the forward read. In the reverse read, the large peak indicates “G” and the small peak indicate “C”. B: In the forward read, the large peak indicates “G” (wild-type) and the small peak indicates “G” (G145A) in the forward read. In the reverse read, the large peak indicates “C” and the small peak indicate “G”
