EAHAD F9 Database Latest News (February 2020)

An extensive programme of revision of published and unpublished data has been undertaken over the last 12 months. Many corrections and amendments have been made, for example updating of Human Genome Variant Society (HGVS) variant definitions, together with removal of duplicate case entries. In addition more than 1000 additional cases (including 92 previously undescribed variants) have been added during February 2020.
See Citing Us (below) for information on our recent EAHAD-DB publication.
