Molecular genetic analysis of the F11 gene in 14 Turkish patients with factor XI deficiency: identification of novel and recurrent mutations and their inheritance within families.
Curiously, although the index patient inherited both Bernard Soulier syndrome and factor XI deficiency (FXI: C = 1.3%), he had mild bleeding symptoms restricted only to ecchymoses and petechiae.
We therefore concluded that the insertion of 15 nucleotides in the F11 gene is the causative mutation for factor XI deficiency in Japanese black cattle.
To determine the utility of single-stranded conformation polymorphism (SSCP) analysis for screening mutations in the factor XI (fXI) gene, we investigated three patients with heterozygous factor XI deficiency.
