The algorithm to left align an indel; biallelic or multiallelic is as follows:
[[Image:variant_normalization_algorithm.png|none|500px|Lines 1 to 3 ensures parsimonious representation on the left side. Lines 4 to 9 performs the left alignment and ensures parsimonious representation on the right side. Although we refer to this as a left alignment, this algorithm also ensures a parsimonious representation of Indels. In the case of STRs, we might prefer the repeat units be retained.]]
