However, although presenting greater genetic diversity, the Amazon biome showed positive inbreeding coefficients (F IS ) in three of the four locations, ranging from 0.0855 to 0.2421, indicating a potential risk of genetic erosion, possibly related to the increased degradation of this biome in recent decades.

While most of the genetic diversity associated with disease trait variation is shared among worldwide populations, a fraction of this component is expected to be unique to each continental group, including Indigenous Americans. Here, I describe the current state of knowledge from genome-wide association studies on Indigenous populations, as well as non-Indigenous populations with partial Indigenous ancestries from the American continent, focusing on disease susceptibility and anthropometric traits. While some studies identified risk alleles unique to Indigenous populations, their effects on trait variation are mostly small. I suggest that the associations rendered by many inter-population studies are probably inflated due to the absence of socio-cultural-economic covariates in the association models. I encourage the inclusion of admixed individuals in future GWAS studies to control for inter-ancestry differences in environmental factors. I suggest that some complex diseases might have arisen as trade-off costs of adaptations to past evolutionary selective pressures. Finally, I discuss how expanding panels with Indigenous ancestries in GWAS studies is key to accurately assess genetic risk in populations from the American continent, thus decreasing global health disparities.","PeriodicalId":12557,"journal":{"name":"Genetics and Molecular Biology","volume":"9 1","pages":"e20230024"},"PeriodicalIF":2.1,"publicationDate":"2024-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142217263","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study evaluated the gene expression of NLRP1, NLRP3 and IL-1β in individuals with DS, aiming to understand their susceptibility to immune-mediated diseases. In addition, we assessed whether the individuals with DS present a differential inflammatory response after in vitro infection using PBMCs. For the gene expression assay, 20 individuals with DS and 15 healthy individuals for the control group (CT) were included, while the in vitro infection assay included 10 subjects. mRNA levels from individuals with DS group showed 1.9-fold change (FC) downregulation for NLRP1 (p=0.0001), but no differences for NLRP3 and IL1β. We did not observe significant differences between lipopolysaccharide (LPS)-treated and untreated cells in our in vitro assays.
