Also, all SNPs in candidate gene CTLA4, HAVCR1, and SUMO4 had p-values less then 0.05 for the analysis including all cases but some of these p-values were not significant for the analysis including one randomly selected case per family.Table 3Single-SNP case-control analysis for SNPs in 14 candidate genesPower comparisonOur simulation results showed that the weighted composite likel
