Single-nucleotide polymorphisms (SNPs) play a major role in the understanding of the genetic basis of many complex human diseases. Also, the genetics of human phenotype variation could be understood by knowing the functions of these SNPs. It is still a major challenge to identify the functional SNPs in a disease-related gene. This work explored how SNPs mutations in HLA-DRB1 gene could affect renal transplantation rejection. This study was carried out in Ahmed Gasim Hospital, Renal Dialysis Center during the period, from September 2012 to November 2013. Blood samples from five Sudanese patients (different families) with known renal transplantation rejection were collected before hemodialysis, furthermore one blood sample for control. DNA sequences results and detected SNPs were analyzed using bioinformatics tools (BLAST, SIFT, nsSNP Analyzer, PolyPhen, I-mutant, BioEdit, CPH, Chimera, Box shade and Project Hope). In addition, international databases were used for datasets [NCBI, Uniprot]. Results showed that, three SNPs were detected;two of three SNPs were predicted as tolerant or benign (rs1059575, novel) and one was deleterious (rs17885437). This study concluded that the identification of pathological SNPs could be an answer to unknown causes for a lot of organ transplantation rejection cases.展开更多
