Figure 2. Electropherograms of the patient's 5--reductase type 2 gene (SRD5A2) exon 4: 1) sense sequence showing thymine (T) heterozygous deletion at position 1998 (GenBank: 338466, L03843) in one allele (allele 1), followed by a heterozygous sequence and a G substitution by A at position 2022 in the other allele (allele 2) compared to a wild-type sequence; and 2) the antisense sequence showing the 2 consecutive mutations.
