Background:
Hemophilia A, an X-linked bleeding disorder, is caused by a complete or partial deficiency in factor VIII. Multiple factors engage in the development and progression of bleeding episodes in hemophilia patients, especially arthropathy.
Objectives:
Detection of macrophage migration inhibitory factor (MIF)-173 G/C polymorphism in people with hemophilia A (PWH) and the possible associations between the type of MIF gene polymorphism and selected disease-related variables.
Patients And Methods:
This case-control study included 95 male patients with hemophilia A and 95 non-hemophiliac subjects, all aged from 2 months to 63 years. An allele-specific polymerase chain reaction (AS-PCR) with a multiplex technique was used to detect MIF polymorphisms.
Results:
A significantly higher frequency of GG polymorphism was reported in the control group (81, 85.3%) compared to PWH (64, 67.4%), while a significantly higher frequency of GC polymorphism was found in PWH (21, 22.1%) than that in healthy subjects (10, 10.5%), P < 0.05. The G allele polymorphism was detected in 90.0% of the control group compared to 78.4% of PWH (149 subjects), while the C allele frequency was higher in PWH (41, 21.6%) compared to that in healthy individuals (18, 10.0%), P < 0.05. The frequencies of varied MIF-173 polymorphisms did not show significant differences among patients with different clinical presentations or in relation to presence of inhibitors, P > 0.05.
Conclusions:
MIF-173 GC polymorphism is seen in PWH more than that in healthy individuals. Further studies are required to detect additional SNPs through sequencing of the MIF gene and to detect MIF serum levels during bleeding episodes.
