    <p>Estimated power levels to detect the DSL using 500–2000 trios, assuming a 10% disease prevalence and additive mode of inheritance. The significance level is set to 5%. For the weighted Bonferroni method (Weighted), the partitioning parameters are <i>K</i> = 7 and <i>r</i> = 2. MAF denotes minor allele frequency. The power reflects the proportion of times the p-value of the DSL (Independence scenario and LD scenario (DSL only)) or a SNP in LD with the DSL (LD scenario (DSL+)) met the weighted Bonferroni (Weighted) or standard Bonferroni corrected (Standard) significance level. The standard Bonferroni correction adjusts for 500 K comparisons.</p

    <p>Results of the CAMP analysis with 402 families, 534,290 SNPs, assuming an additive mode of inheritance. Num. Info. Families indicates the number of families that were informative (i.e., at least one parent was heterozygous) for the marker of interest, and MAF denotes minor allele frequency. Markers with fewer than 20 families were removed from the analysis, as the asymptotic properties required for the test statistic may not hold. The power ranks are obtained from the conditional power of the test, calculated using our new technique with mating type ratio equation R4. The required significance level is obtained using the Ionita-Laza method <a href="http://www.plosgenetics.org/article/info:doi/10.1371/journal.pgen.1000197#pgen.1000197-IonitaLaza1" target="_blank">[9]</a> with <i>K</i> = 7, <i>r</i> = 2, and α = 0.05.</p

    <p>Estimated power levels to detect the DSL using 2000 trios, assuming a 10% disease prevalence. The significance level is set to 5%. For the weighted Bonferroni method (Weighted), the partitioning parameters are <i>K</i> = 7 and <i>r</i> = 2. “Under True Gen. Model”, Add. refers to the scenario where the true (but “unknown”) model is additive (as the results are analyzed using all three genetic models). Similar scenarios are provided for the dominant (Dom.) and recessive (Rec.) genetic models. MAF denotes minor allele frequency. The power reflects the proportion of times the p-value of the DSL (Independence scenario and LD scenario (DSL only)) or a SNP in LD with the DSL (LD scenario (DSL+)) met the weighted Bonferroni (Weighted) or standard Bonferroni corrected (Standard) significance level. The standard Bonferroni correction adjusts for 1.5 M comparisons (500 K markers <sup>*</sup> 3 genetic models).</p

    Genotyping error models.

    <p>The three genotype clusters represent the clouds generated from intensity plots. The AA cluster consists of all homozygous minor calls, the AB cluster heterozygous calls and the BB homozygous major calls. Each arrow represents one of the genotyping error models considered. For example, in Model #6 minor homozygotes (AA) can be miscalled as heterozygotes (AB).</p

    <p>Significance threshold at an overall <i>α</i>-level of 5% for <i>χ</i><sup>2</sup>-statistics adjusted for 41 comparisons using Bonferroni-correction: 10.46.</p><p>The genome-wide transmission test statistic, , is reported for each CEPH proband with both parents genotyped, ordered by Pedigree ID. Each statistic is calculated using all available SNPs (Column 3), all concordant SNPs (Column 4) and the SNPs appearing on only one platform (Column 5). Test statistics using all concordant SNPs that are larger than the Bonferroni-adjusted value of 10.46 are presented in bold.</p
