| Left aligning a variant means shifting the start position of that variant to the left till it is no longer possible to do so. It is a concept associated with insertion and deletion variants and describes specifically the nature of a position of a variant as opposed to its length. In order to further differentiate left alignment from simply left padding a variant, the definition is as follows: | | Left aligning a variant means shifting the start position of that variant to the left till it is no longer possible to do so.

| The following figure shows examples of an unnormalized short tandem repeat which is a special class of indels. The colour of the text is synchronized to the variant it is describing in the figure. | | The following figure shows examples of an unnormalized short tandem repeat which is a special class of indels.
