Variant Type

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.
