background: heterogeneous mutations in the human coagulation factor ix gene lead to an x-linked recessive bleeding disorder known as hemophilia b. the disease is distributed worldwide with no ethnic or geographical priority. materials and methods: the aim of this study was to characterize the factor ix gene mutations in 28 unrelated iranian hemophilia b patients. polymerase chain reaction (pcr)...

The fourth component of complement (C4) is encoded by two closely linked genes (C4A and C4B) within the MHC. Null alleles at either locus (C4AQO or C4BQO) are relatively common, occurring at the C4A locus in 10% of normal individuals and at the C4B locus in 16% of normal individuals. However, the presence of the double null haplotype (C4A * QO,B * QO) on the same chromosome is extremely rare. W...

conclusions our investigation demonstrated that there is a highly significant association between the studied alleles and t1d. it can be construed that haplotype hla-dr3-dq2 has a very modest effect with respect to the risk of t1d. patients and methods this study was a case-control study. the number of samples was determined using the cochran formula. eighty unrelated t1d patients, including 42...

Large-scale haplotype association analysis, especially at the whole-genome level, is still a very challenging task without an optimal solution. In this study, we propose a new approach for haplotype association analysis that is based on a variable-sized sliding-window framework and employs regularized regression analysis to tackle the problem of multiple degrees of freedom in the haplotype test...

Suspicion of failure in the effectiveness artemisinin-based combination therapies (currently first-line treatment malaria, worldwide) is leading to unofficial use alternative antimalarials, including chloroquine and sulfadoxine/pyrimethamine, across northern Nigeria. To facilitate evidence-based resistance management, antimalarial mutations were investigated Plasmodium falciparum multidrug resi...

BACKGROUND MLF2 was the candidate gene associated with coccidiosis resistance in chickens. Although single marker analysis supported the association between MLF2 and coccidiosis resistance, causative mutation relevant to coccidiosis was not identified yet. Thus, this study suggested segregation analysis of MLF2 haplotype and the association test of the other candidate genes using improved data ...
