-- **Positive Delta LLR ($> 1.5$)**: The wildtype amino acid is significantly more evolutionarily favored by natural selection across the phylogenetic tree. The mutation disrupts biophysical stability or catalytic activity -> **Pathogenic / Deleterious**.

+- **Positive ΔLLR (> 1.5)**: The wildtype amino acid is significantly more evolutionarily favored across the phylogenetic tree. The mutation disrupts biophysical stability or catalytic activity → **Pathogenic / Deleterious**.
+- **Neutral / Negative ΔLLR (≈ 0 or < 1.5)**: The substitution is evolutionarily tolerated → **Benign / Tolerated**.
