Positions as String

[pnrobinson]

In the GenomicInterpretation, variant positions are emerging as strings. I am trying to trace down where this happens. At line 115 of Retinoblastoma, we are still ok

acmg_pathogenicity_classification: PATHOGENIC
therapeutic_actionability: ACTIONABLE
variation_descriptor {
  variation {
    copy_number {
      allele {
        sequence_location {
          sequence_id: "refseq:NC_000013.14"
          sequence_interval {
            start_number {
              value: 25981249
            }
            end_number {
              value: 61706822
            }
          }
        }
      }
      number {
        value: 1
      }
    }
  }
  extensions {
    name: "mosaicism"
    value: "40.0%"
  }
}
