This algorithm categorizes the variant as one of the following:

  • SNP: Single nucleotide substitution

  • MNP: Multiple nucleotide substitution of same length

  • Insertion: Insertion of nucleotides against the reference

  • Deletion: Gap compared to the reference sequence

  • DeletionInsertion: Multiple nucleotides replaced with differing lengths

  • Complex: More than one variant type

  • Reference: Only a single allele

Requirements

None

Output

A Variant Type column is created containing the variant categorization.
