Based on the nucleotide context, the authors suggest that a new mutational mechanism may be at work involving cytosine
deamination of single - stranded DNA (presumably during replication).
The SureSeq mix increases the success and accuracy of hybridization - based NGS for FFPE samples by repairing damage such as nicks and gaps, oxidized bases, blocked 3» ends, and
deamination of cytosine to uracil.

The recovered DNA sequences exhibited signatures
of postmortem DNA damage typical
of ancient DNA, with preferential fragmentation at purines and inflated rates
of cytosine
deamination at single - stranded overhangs (19, 20).
