Advanced Search

  • Variants can be retrieved using any combination of the following search criteria.
  • If nothing is entered via checkboxes or dropdown lists, the search will return variants over the entire range of the FIX protein or F9 gene.
  • Codons are numbered with respect to the HGVS nomenclature-with codon 1 representing the first residue (Met) of the signal peptide, or alternatively using the LEGACY numbering of earlier publications where codon 1 refers to the first Tyr of the mature secreted FIX protein.
