# Genomics API . variants

## Instance Methods

Creates a new variant.

Deletes a variant.

Gets a variant by ID.

Creates variant data by asynchronously importing the provided information. The variants for import will be merged with any 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. In particular, this means for merged VCF variants that have conflicting INFO fields, some data will be arbitrarily discarded. As a special case, for single-sample VCF files, QUAL and FILTER fields will be moved to the call level; these are sometimes interpreted in a call-specific context. Imported VCF headers are appended to the metadata already in a variant set.

Updates a variant. This method supports patch semantics. Returns the modified variant without its calls.

Gets a list of variants matching the criteria. Implements [GlobalAllianceApi.searchVariants](https://github.com/ga4gh/schemas/blob/v0.5.1/src/main/resources/avro/variantmethods.avdl#L126).

### Method Details

`create(body, x__xgafv=None)`

    Creates a new variant.

`import_(body, x__xgafv=None)`

    Creates variant data by asynchronously importing the provided information. The variants for import will be merged with any 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. In particular, this means for merged VCF variants that have conflicting INFO fields, some data will be arbitrarily discarded. As a special case, for single-sample VCF files, QUAL and FILTER fields will be moved to the call level; these are sometimes interpreted in a call-specific context. Imported VCF headers are appended to the metadata already in a variant set.

    Args:
      body: object, The request body. (required)
        The object takes the form of:

        "error": { # The `Status` type defines a logical error model that is suitable for different programming environments, including REST APIs and RPC APIs. It is used by [gRPC](https://github.com/grpc). The error model is designed to be: - Simple to use and understand for most users - Flexible enough to meet unexpected needs # Overview The `Status` message contains three pieces of data: error code, error message, and error details. The error code should be an enum value of [google.rpc.Code][google.rpc.Code], but it may accept additional error codes if needed. The error message should be a developer-facing English message that helps developers *understand* and *resolve* the error. If a localized user-facing error message is needed, put the localized message in the error details or localize it in the client. The optional error details may contain arbitrary information about the error. There is a predefined set of error detail types in the package `google.rpc` which can be used for common error conditions. # Language mapping The `Status` message is the logical representation of the error model, but it is not necessarily the actual wire format. When the `Status` message is exposed in different client libraries and different wire protocols, it can be mapped differently. For example, it will likely be mapped to some exceptions in Java, but more likely mapped to some error codes in C. # Other uses The error model and the `Status` message can be used in a variety of environments, either with or without APIs, to provide a consistent developer experience across different environments. Example uses of this error model include: - Partial errors. If a service needs to return partial errors to the client, it may embed the `Status` in the normal response to indicate the partial errors. - Workflow errors. A typical workflow has multiple steps. Each step may have a `Status` message for error reporting purpose. - Batch operations. If a client uses batch request and batch response, the `Status` message should be used directly inside batch response, one for each error sub-response. - Asynchronous operations. If an API call embeds asynchronous operation results in its response, the status of those operations should be represented directly using the `Status` message. - Logging. If some API errors are stored in logs, the message `Status` could be used directly after any stripping needed for security/privacy reasons. # The error result of the operation in case of failure.

`search(body, x__xgafv=None)`

    Gets a list of variants matching the criteria. Implements [GlobalAllianceApi.searchVariants](https://github.com/ga4gh/schemas/blob/v0.5.1/src/main/resources/avro/variantmethods.avdl#L126).

    Args:
      body: object, The request body. (required)
        The object takes the form of:

        "end": "A String", # The end of the window, 0-based exclusive. If unspecified or 0, defaults to the length of the reference.
        "pageSize": 42, # The maximum number of variants to return. If unspecified, defaults to 5000.
        "pageToken": "A String", # The continuation token, which is used to page through large result sets. To get the next page of results, set this parameter to the value of `nextPageToken` from the previous response.
        "maxCalls": 42, # The maximum number of calls to return. However, at least one variant will always be returned, even if it has more calls than this limit. If unspecified, defaults to 5000.
        "start": "A String", # The beginning of the window (0-based, inclusive) for which overlapping variants should be returned. If unspecified, defaults to 0.
        "callSetIds": [ # Only return variant calls which belong to call sets with these ids. Leaving this blank returns all variant calls. If a variant has no calls belonging to any of these call sets, it won't be returned at all. Currently, variants with no calls from any call set will never be returned.

        ],
        "variantName": "A String", # Only return variants which have exactly this name.
        "referenceName": "A String", # Required. Only return variants in this reference sequence.
        "variantSetIds": [ # At most one variant set ID must be provided. Only variants from this variant set will be returned. If omitted, a call set id must be included in the request.
