Haemophilia A (HA) is an X-linked recessive hereditary bleeding disorder affecting one in 5000 men, resulting from mutations in the F8 gene. Our objective was to identify the spectrum of mutations of the F8 gene in Lebanese patients, and to perform genotype/phenotype correlations. A group of 79 HA patients from 55 unrelated families was studied. Patients were screened for intron 22 and intron 1 inversion using PCR. In the absence of mutations in both introns, a dHPLC screening followed by a DNA sequencing of all coding regions was performed. When patients presented novel mutations, 150 control chromosomes were tested to exclude common polymorphisms. Large deletions were confirmed by MLPA technique. The mRNA was specifically studied whenever a splice site mutation was detected. In addition, studies of the putative biochemical function and FVIII 3D structures were conducted. Thirty-four mutations were identified in this study of which 21 were novel: 11 missense, two nonsense, two splice sites, five small deletions and one large deletion. Inhibitor found in three over 75 patients correlated with large deletion, intron 22 inversion, and nonsense mutations. We were able to identify all causative mutations in those HA patients. This knowledge represents a huge step for genetic counselling.
