# Genomics API . variantsets

## Instance Methods

Deletes the contents of a variant set. The variant set object is not deleted.

Gets a variant set by ID.

Merges the given variants with existing variants. Each variant will be merged with an existing variant that matches its reference sequence, start, end, reference bases, and alternative bases. If no such variant exists, a new one will be created.

Updates a variant set's metadata. All other modifications are silently ignored. Returns the modified variant set. This method supports patch semantics.

Returns a list of all variant sets matching search criteria.

Updates a variant set's metadata. All other modifications are silently ignored. Returns the modified variant set.

`mergeVariants(variantSetId, body)`

    Merges the given variants with existing variants. Each variant will be merged with an existing variant that matches its reference sequence, start, end, reference bases, and alternative bases. If no such variant exists, a new one will be created.

    When variants are merged, the call information from the new variant is added to the existing variant, and other fields (such as key/value pairs) are discarded.

    Args:
      variantSetId: string, The destination variant set. (required)
      body: object, The request body. (required)
        The object takes the form of:

    {
        "variants": [ # The variants to be merged with existing variants.
          { # A Variant represents a change in DNA sequence relative to some reference. For example, a Variant could represent a SNP or an insertion. Variants belong to a variant set.

            "end": "A String", # The end position (0-based) of this variant. This corresponds to the first base after the last base in the reference allele. So, the length of the reference allele is (end - start). This is useful for variants that don't explicitly give alternate bases, for example large deletions.

              { # A Call represents the determination of genotype with respect to a particular variant. It may include associated information such as quality and phasing.

If a variant had a referenceBases value of T and an alternateBases value of ["A", "C"], and the genotype was [2, 1], that would mean the call represented the heterozygous value CA for this variant. If the genotype was instead [0, 1], the represented value would be TA. Ordering of the genotype values is important if the phaseset is present. If a genotype is not called (that is, a . is present in the GT string) -1 is returned.

              "A String",
            ],
