Notes.

^aSNPs means single nucleotide polymorphisms, referred to covered regions, the first nucleotide of the translation start codon was designated +1, with the next upstream nucleotide being −1.

^b5′ regulatory region = 5′ flanking and untranslated region; 3′ regulatory region = 3′ flanking and untranslated region.
