Case Previous Testing: The mRNA ref seq were, wherein the “A” nucleotide of the start codon ATG constituted as +1 numbering of the cDNA sequence. Met encoded by the start codon ATG also represented +1 for the amino acid numbering as set forth by the preprotein seq. PolyPhen-2, SIFT, and I-Mutant 3 tools were used for predicting the potential impact of an amino acid alteration in missense mutations on the function of each enzyme.
