PhyloP was used as a conservation score rating the nucleotides from “not conserved” (−14.1) to “highly conserved” (6.4). Align GVGD score: most likely deleterious (C65) to least likely deleterious (C0) GV (Grantham variation) and GD (Grantham deviation). The Grantham distance was used to evaluate physicochemical changes in amino acids (0 = no physicochemical changes; 215 = large changes). In silico predictions were performed using PolyPhen-2 (Polymorphism Phenotyping-2), SIFT (Sorting Intolerant from Tolerant) score: <0.05 deleterious, >0.05 tolerated, and Mutation Taster: disease causing variants (p value = 1.0), might not be disease causing (p value <0.99).
