We are dedicated to the smaller subsets of the ultra-rare or orphan bleeding disorders community. Since 2012, the Factor 7 Retreat (for individuals and families living with FVII deficiency), and later followed by the Glanzmann’s Thrombasthenia Symposia, have both offered program experiences for those with rare bleeding disorders.
The Factor 7 Retreat and GT Symposia are now a part of the One Drop program.
