F5 Variants and DB Features: Protein Structure Now Added

Variants in the gene (F5) that codes for coagulation factor V (FV) may be associated both with rare FV deficiency and bleeding, but also with more common prothrombotic (hypercoagulable) states.

There are currently 209 unique variants in the F5 gene compiled within this database corresponding to 443 individual cases from c.280 different families. Approximately half the cases are single reports, the remainder taken from 64 families with multiple described cases.

In order to help interpret their significance in real-life cases, we provide amino-acid alignments (to assist in estimating the effects of missense variants), together with information on common variants of F5. Read the Help Page for a more detailed feature description.
