Repeat Expansion Variant Table and Cards

Repeat Expansion Variant Table

The Repeat expansion analysis variant table contains the following information:

  • Position: chromosome and position of the repeat expansion.
  • Display repeat unit: display repeat unit familiar to the clinician.
  • Repeat unit: repeat unit in the reference orientation.
  • Pathogenicity: repeat expansions can be classified as:
      • Pathogenic: the number of repeats detected in the sample is equal to or greater than the minimum number of pathogenic repeats.
      • Uncertain Significance: the number of repeats detected in the sample is greater than the maximum normal number of repeats but less than the minimum number of pathogenic repeats.
      • Benign: the number of repeats detected in the sample is smaller than or equal to the normal number of repeats.
  • Genes: in which gene the repeat expansion has been found.
  • Sample repeats: number of repeats observed in the allele.
    • MIN pathogenic repeats: minimum number of repeats needed to consider the variant pathogenic.
    • Normal MAX repeats: maximum number of repeats allowed to call the variant as normal.
    • Ref. genome repeats: number of repeats in the reference genome.
  • Zygosity
  • Filters: VCF filters.

Repeat expansion cards:

  • Variant: general variant information and region browser.
  • Gene: it contains the same gene cards as the ones displayed under the gene level of the main analysis (small variant table).
