EAHAD DBs Latest: Mar 2022 - F7 Database Updated to End 2021
See Citing Us (below) for links to our recent EAHAD-DB publications.
F10 Variants and DB Features
Variants in the gene (F10) that codes for coagulation factor X (FX) may be associated with rare FX deficiency and bleeding. There are currently
181 unique variants in the F10 gene compiled within this database corresponding to
631 individual cases from 385 different families. Approximately half the cases are single reports, the remainder taken from 97 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).

Reference Sequences and Nomenclature (HGVS and Legacy)
The reference sequence used for FX protein is NP_000495.1 and its corresponding stable Locus Reference Genomic DNA sequence (LRG) is LRG_548. Codons and amino-acids are numbered on this site in two ways. In HGVS numbering, codons are numbered with codon +1 coding for the first residue (Met) of the 40-residue signal peptide/propeptide (this is -40 in Legacy numbering). In Legacy numbering, codon +1 refers to that coding for the first amino-acid of the mature FX protein (in HGVS numbering, this is codon +41). HGVS numbering is recommended, however Legacy numbering is sometimes used in earlier FX publications.
Protein Structure Representations
All structural analysis of the missense variants presented within this database uses the full length
human FXa structure model kindly provided by Dr Divi Venkateswarlu, Department of Chemistry, N Carolina Agricultural & Technical State University, USA. (Venkateswarlu et al, Biophys J 2002 Vol 82: 1190-1206
PMID No 11867437). EAHAD-DB are most grateful for provision of this model.
Construction of the human FXa model included crystal data on human FXa EGF2-SP (PDB file 1XKA) from Kamata et al (PNAS USA (1995) 95: 6630); and human FVIIa Gla-EGF1 (PDB file 1DAN) from Banner et al (Nature (1996) 80: 41-46).
