Background: Vitamin D plays a role in critical cellular processes such as apoptosis, cell development, and division. The Fok1 polymorphism in the VRD gene is T/C resulting in larger vitamin D receptor protein with lesser expression activity. Fok1 polymorphism is thought to be linked to many diseases including diabetes mellitus, cancers, and rheumatoid arthritis. The snipe also provides effective and sensitive diagnostic and predictive tools and affected by differences in ethnicity and individuals' life style. This study reports on the frequency and distribution of Fok1 SNP among healthy Sudanese transplantation donors. Method: This cross sectional study was conduct in National Cancer Institute University of Gezira, Sudan. One hundred and forty six healthy Sudanese transplantation donors were enrolled in this study. Two ml of venous blood was collected from each participant and stored at -20 till DNA extraction. Qaigen kit was used for DNA extraction. VDR Fok1 was genotyped by CTPP-PCR with proper primers designing and PCR condition. Data was collected by structured questionnaire and analyzed by SNP Stats online tool and medical calculator. Results: According to study results theFok1 polymorphism distributed among Sudanese with percentage of 49.9% (TT + CT), frequency of SNP variants was 69.8% regarding C allele and 30.2% for T allele, while the three genotypes was 10.2% for TT, 39.7% for TC and 50.1% for CC genotype. Conclusion: The frequency of Fok1 VDR SNP was high among healthy Sudanese transplantation donors, this necessitate the conduction of wide area survey among other healthy Sudanese population. This intern will help in investigating the nature of the relation of this SNP with other different diseases. Keywords: Vitamin D, Fok1rs. 2225870, VDR SNP, Sudanese |
