Custom annotation sources

You can create custom annotation sets in Ion Reporter™ Software. A custom annotation set is a type of workflow preset that you can add to an analysis workflow so that you can launch analyses that use the custom annotation set.

Ion Reporter™ Software includes two gene models: RefGene and Ensembl. Only one gene model can be added to any custom annotation set.

Use the following guidelines to create custom annotation sets.

  • To use an Ion Reporter™ Software canonical transcript set, you must use the compatible gene model when you select an annotation source. For example, use the RefGene gene model with the Refseq canonical transcript set.
  • To create a custom annotation set with Polyphen and SIFT scores, ensure that you use the corresponding RefSeq or Ensembl gene model. For more information, see Effect of Ensembl and RefSeq sources on Polyphen and SIFT scores.
  • To create a custom annotation set that includes any of the following predefined annotation sources in the custom annotation set, a gene model must be also included in the annotation set.

    IMPORTANT! A custom annotation source that uses the following annotation sources without a gene model (RefGene and Ensembl) will result in unexpected analysis results because the custom annotation source is unable to annotate variants.

    Variants are annotated with the genes in the gene model for the predefined annotation sources in the following order:
    • OMIM

    • DRUGBANK

    • DRA

    • GO

  • A gene model must be also included in the annotation set that is used to create a custom annotation source, such as a gene set or custom transcript set, if the annotation set includes any of the following predefined annotation sources:
    • Custom geneset
    • Custom Transcripts
