  • Most of the mutations were predicted to be pathogenic by at least two prediction algorithms.

  • A SIFT score of ≤0.05 indicates the amino acid substitution is pathogenic (damaging), whereas a score of ≥0.05 is predicted to be tolerant. PolyPhen predicts results of nsSNPs as possibly damaging and probably damaging (PSIC >0.5) or benign (PSIC <0.5). According to CADD classification, variants with a C-score of 10 or greater (≥C10) are probable functional variants, variants with a C-score of 20 or greater (≥C20) are most deleterious and variants with a C-score of 30 or greater (≥C30) are lethal. Pathogenic mutation scores are highlighted in bold.

  • ALT, altered; CADD, combined annotation dependent depletion; Chr, chromosome; CRC, colorectal cancer; NA, not applicable; PSIC, position-specific independent counts; POS, position; REF, reference; SIFT, sorting intolerant from tolerant.
