From: Malignant melanoma arising from a perianal fistula and harbouring a BRAFgene mutation: a case report
Sequence chromatograms of the negative control, the fistula melanoma and the positive control DNA samples. A) DNA from peripheral blood of the fistula melanoma patient with an arrow showing the wild-type genotype (the T allele in homozygosis). B) DNA from the perianal fistula melanoma showing the T1799A mutation in heterozygosis (arrow). C) DNA from melanoma cell line A375, with the mutation in the homozygous state.
