Custom Annotations

Custom Annotations allows you to attribute annotations (labels, scores, and population frequency) to variants or variants within a genomic region. The supported data categories for custom annotation in Connected Insights are as follows:

  • Filter: String labels

  • Score: Numeric values

  • AlleleFrequency: Allele frequency for population frequency data

When matching annotations for large variants (structural variants and copy number variants), by default Annotation Overlap (measured as the total overlap divided by the length of the annotation) of >= 0.75 is used, but can be changed to Reciprocal Overlap (measured as the total overlap divided by either the length of the annotation or the length of the variant, whichever is larger) by specifying Reciprocal Overlap in the Description column for the annotation. For more information, refer to Custom Annotation File Format.
