According to the HGVS nomenclature, mutation representations of Human F9 follow NCBI's NM_000133.3 (mRNA) and NP_000124 (Protein) as the reference sequences. In case you have used a different sequence, please mention which one in the above sequence reference text box.

The numbering generally should follow the HGVS format where in the A of the ATG of the methionine is +1. If you have followed a different numbering (for eg., first residue of Gla numbered as +1 leaving out the Signal Peptide, then please indicate it in the above Sequence numbering text box.

If you have a considerable number of variants to submit and would like to submit a spreadsheet, please contact us for more information at s.perkins@ucl.ac.uk .
