“…Studies of sequence variation in catsup show precisely how pleiotropy can be subdivided by single nucleotide polymorphisms [82]. A recent analysis of quantitative trait loci in mice is also consistent with this idea, showing that individual alleles observed in quantitative genetic mapping studies are less pleiotropic than was indicated by developmental genetic analysis [86]. Taken together, these studies suggest that mutations that somehow subvert a gene's pleiotropic effects may be over-represented in natural populations.…”

“…Pleiotropy, defined here as one gene affecting more than one phenotype, has become increasingly important in interpreting both genotype-phenotype maps and underlying factors that affect comorbidity, and has been integrated into several methods for genome wide association studies (GWAS) (Chung et al 2014;Hill and Zhang 2012;Lee et al 2012;Li et al 2014a, b;Pendergrass et al 2013;Rzhetsky et al 2007;Sivakumaran et al 2011;Solovieff et al 2013;Stearns 2010;Wagner et al 2008;Wagner and Zhang 2011;Yang et al 2015). Studies of pleiotropy can impact our understanding of underlying disease processes, and implicitly, the prevention and treatment of disease as well as predicting adverse reactions to drugs.…”

“…et al 2007;Sivakumaran et al 2011;Solovieff et al 2013;Stearns 2010;Wagner et al 2008;Wagner and Zhang 2011;Yang et al 2015), little has been done to investigate the relationship between pleiotropy and risk variation as measured by effect sizes. Studies investigating this question have focused on exploring the correlation of effect sizes of different traits associated with a single locus; however, no study has investigated the relationship between effect size and the degree of pleiotropy in humans.…”

“…Essa semelhança no padrão de modularidade entre clados que divergiram a algumas dezenas de milhões de anos e evoluíram em contextos biogeográficos diferentes Marroig e Cheverud, 2001;Bininda-Emonds et al, 2007;O'Leary et al, 2013) sugere que: o padrão de modularidade dos mamíferos eutérios esteja relacionado a processos básicos de desenvolvimento e/ou de funções que sejam comuns aos diferentes grupos. Esses processos, por sua vez, devem ter sido mantidos por seleção estabilizadora atuando na manutenção dos efeitos pleiotrópicos responsáveis pela estruturação modular observada no nível fenotípico (Ehrich et al, 2003;Cheverud et al, 2004;Estes e Arnold, 2007;Wagner et al, 2008). Os Xenarthra, no entanto, apresentaram valores relativamente elevados para avg+/avg-em relação aos demais mamíferos eutérios, principalmente para as sub-regiões oral e nasal.…”

“…Isso porque a modularidade observada no nível fenotípico é provavelmente o reflexo da estruturação modular no nível genotípico, que, por sua vez, é condicionado por efeitos pleiotrópicos (Pavlicev et al, 2007;Wagner et al, 2008). Uma das possibilidades para geração de variação genética da pleiotropia é a epistasia diferencial atuando sobre os efeitos pleiotrópicos que determinam os módulos fenotípicos Pavlicev et al, 2007).…”
