  Background: Hemophilia B is an X-linked recessive disorder caused by mutations in the coding sequence of F9 gene, leading to dysfunctional Factor IX (FIX) protein. Objectives: This study is to identify novel and recurrent mutations in hemophilia B patients. Method and Materials: In this study, 9 hemophilia B patients were screened on 8 exons using polymerase chain reaction (PCR) and direct sequencing. Results: We identified 6 point mutations, including 4 missense mutations and 2 nonsense mutations. One of the six point mutations is a novel mutation (NM_000133.3:c.230T>G) which has not been reported previously in hemophilia B database. Single nucleotide transversion of Thymine to Guanine occurs at nucleotide position 230, leading to amino acids substitution from Valine to Glycine at cod.. View More»
