ABSTRACT
<p><b>OBJECTIVE</b>To investigate the genetic linkage between several cytokine and cytokine-related receptor gene loci and essential hypertension (EH) in Chinese.</p><p><b>METHODS</b>Linkage between seven genetic markers and EH in 95 Chinese nuclear families with EH (including 477 subjects) was analyzed using a technique of fluorescence-based gene scan with DNA short tandem repeat loci. These markers were selected from the chromosomal regions nearby eight cytokines and their receptor genes. The two-point non-parametric linkage analysis (NPL), maximum Lod score and transmission/disequilibrium test (TDT) with GENEHUNTER software package were used in this study.</p><p><b>RESULTS</b>Result of TDT showed significant transmission disequilibrium between D14S61 and EH (Chi square 14.29,P=0.00016) although NPL and Lod score revealed no significant linkage (Z=0.78, P>0.05 and Lod score =0.72 respectively) at this locus. No linkage between other loci typed and EH was found by the three genetic analysis methods (P>0.05 or Lod score<-1).</p><p><b>CONCLUSION</b>Alleles at D14S61 were of significant transmission disequilibrium in affected siblings. Transforming growth factor beta 3 is 0.1 cM away from D14S61, which suggests that the relationship between genes at or near this regions and EH needs to be further explored.</p>
