3.4.21.27 | S248N |
binds platelets with 5fold reduced affinity compared with wild-type, the A3 domain is probably not affected significantly, as FXI-Asn248 is secreted, activated by activated factor XII, and activates FIX similar to wild-type activated factor IX. Is associated with bleeding and defective FXI binding to platelets but does not affect the activated partial thromboplastin time assay, which does not contain platelets |
