We identified 14 independent loci associated (P < 5 × 10 −8) with estradiol levels in males, of which 1 (CYP3A7) was genome-wide and 7 nominally (P < 0.05) significant in females.In addition, 1 female-specific locus was identified. Most loci contain functionally relevant genes that have not been discussed in relation to estradiol levels in …

WebJan 1, 2010 · The inbreeding coefficient F is somewhat preferable to heterozygosity as the metric of interest, because the latter is dependent on the specific distribution of minor allele frequencies of SNPs in the GWAS panel in question. In practice, however, this makes little odds unless different individuals have been typed on different GWAS panels, and ... WebMay 7, 2024 · With the goal of emulating standard GWAS pipelines, we incorporated common quality control filters for genotype missing rate, heterozygosity rate, minor allele frequency, and departure from the ... WebFeb 20, 2024 · By dividing the whole association panel into subpopulations and performing GWAS with both linear mixed models and multi-locus mixed-models, we revealed hundreds of significant loci harboring novel candidate genes as well as most of the known flowering time genes. In total, 127 hotspots were detected in at least two GWAS. michael ketcham md
