a. The range of the PMut prediction score is from 0 to 1; a score over 0.5 suggests an effect on protein function and a score <0.5 indicates that the substitution is likely neutral. The range of the reliability index is from 0 to 9; the higher the number, the more reliable is the prediction.

b. PolyPhen Scores: 1.49–1.25 are designated as "Potentially damaging to function"; 1.24–1.00, "Borderline"; and <1.00, "Benign".

c. The SIFT scores are limited to the range of 0.0 to 1.0. Variants are classified as "Intolerant" (0.00–0.05), "Potentially intolerant" (0.051–0.10), "Borderline" (0.101–0.20), and "Tolerant" (0.201–1.00).
