Genotyping of Intron Inversions and Point Mutations in Exon 14 of the FVIII Gene in Iranian Azeri Turkish Families with Hemophilia A.
Hemophilia A (HA) is an inherited X-linked bleeding disorder caused by a variety of mutations that are distributed throughout the largeFVIIIgene (F8). The most common mutations in studied populations with severe HA are introns 22 and 1 inversions, gross exon deletions and point mutations in exon 14. The aim of this study was to define the frequency of these common mutations in Iranian population of Azeri Turkish in North West of Iran. Fifty patients with severe HA and forty-three female potential carriers were genotyped by inverse shifting polymerase chain reaction (IS-PCR), long-range PCR, multiplex PCR, and sequencing methods for the detection of Intron 22 and 1 inversions, gross exon deletions, and exon 14 point mutations, respectively.F8intron 22 inversion was detected in 22 (44 %) out of 50 patients. Moreover, we detected one intron 1 inversion (2 %), and one point mutation in exon 14 (2 %). In this population, 52 % of the patients with hemophilia A did not show to carry a mutation in the analyzed regions by three mentioned methods.F8intron 22 inversion was the major causative mutation in nearly 50 % of severe HA cases in an Azerbaijani Turkish population, which is similar to the incidence of other populations. IS-PCR is a robust, rapid, efficient, and cost-effective method for the genetic analysis of patients with severe HA and for HA carrier detection, especially in developing countries.
