In this study, we used single-stranded conformational polymorphism (SSCP) and conformational sensitive gel electrophoresis (CSGE) methods and direct sequencing to identify the mutation responsible for haemophilia A in our patient.<h4>Conclusions</h4>We reported a novel missense mutation (GAA→GGA), E1623G, in exon 14 of FVIII gene that is associated with moderate haemophilia A. This new mutation was recorded in GenBank (NCBI) with accession number JF916726.1. Here, F8 is linked to hemophilia A.
