Variant Nomenclature mapping to OMOP Genomic vocab variants

Hi,
We are starting to look at mapping variant details to the OMOP genomic vocabulary. The source data includes variations using a nomenclature system like the one described in Nomenclature for the description of sequence variations (mutation nomenclature) and would like to map them to the genomic vocabulary. Usagi isn’t particularly useful in terms of picking up the matches and so thought it may be useful to parse these into text that is similar to that which is contained within the genomic vocab which may give us more hits with usagi or atleast closer matches. Is this the direction we should be heading in and if so does anyone know if there are any tools available or that are being worked on?
Thanks,
Tom
