KRAS and colorectal adenoma: For KRAS, eight out of the nine nucleotide positions tested showed sufficient results (codon 12: c.34G>CAT, c.35G>ATC, codon 13: c.38G>ACT, c.39C>AGT, codon 59: c.175G>A, codon 61: c.181C>AG, c.182A>TGC, c.183A>CT) covering 98.85% of the mutations described in colorectal adenomas (Figure 1, Table S1C).
