Аннотация
BACKGROUND: Congenital fibrinogen deficiencies (CFD) are a group of rare bleeding disorders (RBD). Afibrinogenemia as a subclass of these disorders would occurs as a result of mutations in fibrinogen gene. Here in, the sequences of Aα chain of fibrinogen (FGA) in patients with inherited afibrinogenemia disorder in south-eastern of Iran were analysed.
METHODS: The FGA gene exons were amplified using PCR method and the DNA sequences were analysed to study the mutations in Aα chain of Fibrinogen.
RESULTS: Results showed that there was no large deletion in FGA gene. Although a frame shift mutation: c.196_197insT p.Ser66PhefsX10 in a patient and a novel mutation of IVS2-1G>A in two other patients were detected which were different from those detected in European population.
CONCLUSION: Different mutations are responsible of afibrinogenemia deficiency which requires more relevant studies for confirmation. The type and distribution of mutations in fibrinogen gene in Iranian patients is significantly different with reported mutations in European patients.
