So now that we know how to tell if a variant is left aligned or right parsimonious, we simply need to manipulate the variant till the rightmost ends of the alleles are not the same, apply truncation to the superfluous nucleotides on the left side of the variant to obtain a normalized (parsimonious and left aligned) variant.

The algorithm to normalize a variant; biallelic or multiallelic is as follows:
