This study aimed to assess the proportions of inter-ethnic admixture in the Brazilian population of Rio de Janeiro using autosomal Ancestry-Informative Markers (AIMs). The autosomal data were also compared to the results expected from uniparental genetic markers. A total of 413 individuals were genotyped for 46 AIM-Indels and ancestry estimates were then assessed using HGDP-CEPH samples as ancestral reference. Individuals from Rio de Janeiro presented highly diverse admixture patterns. The global admixture estimates showed a predominantly European ancestry, above 55%, followed by African and Amerindian contributions. A separate self-declared Afro-descendant group also included in this study revealed an increased African ancestry, from ∼30% to ∼50%. The inter-ethnic admixture landscape of Rio de Janeiro captured by autosomal AIM-Indels is in agreement with historical records and similar to that expected from uniparental mtDNA and Y-chromosome information. The AIM-Indel panel proved to be a rapid strategy to estimate autosomal genetic ancestry at individual and population levels in Rio de Janeiro, which is useful in population genetics and in case-control association studies.","is_dataset_classified":null,"base_score":4.23410650459726,"endowment":4.23410650459726,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"23151124","pmcid":null,"openalex_id":"https://openalex.org/W2114888149","authors":[],"funders":[],"total_grants":0,"fwci":3.3727,"citation_percentile":0.92837307,"influential_citations":0,"citation_trend":[{"year":2012,"count":1},{"year":2013,"count":5},{"year":2014,"count":7},{"year":2015,"count":5},{"year":2016,"count":8},{"year":2017,"count":3},{"year":2018,"count":7},{"year":2019,"count":7},{"year":2020,"count":9},{"year":2021,"count":3},{"year":2022,"count":1},{"year":2023,"count":8},{"year":2024,"count":3},{"year":2026,"count":1}],"oa_status":"closed","license":null,"oa_locations":[{"url":"http://www.tandfonline.com/doi/pdf/10.3109/03014460.2012.742138","host_type":"publisher"},{"url":"https://doi.org/10.3109/03014460.2012.742138","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/23151124","host_type":"repository"}],"fields_of_study":["Forensic and Genetic Research","Race, Genetics, and Society","Genetic diversity and population structure","Black People","Brazil","Chromosomes, Human, Y","DNA, Mitochondrial","Ethnicity","Female","Gene Frequency","Genetic Markers","Genetic Variation","Genotype","Humans","INDEL Mutation","Indians, South American","Male","Racial Groups","White People"],"mesh_terms":["Brazil","DNA, Mitochondrial","Ethnicity","Female","Gene Frequency","Genetic Markers","Genotype","Humans","Indians, South American","Male","Genetic Variation","Chromosomes, Human, Y","Black People","White People","Racial Groups","INDEL Mutation"],"keywords":["Ancestry-informative marker","Genetic genealogy","Indel","Genetic admixture","Population","Biology","Ethnic group","Genetics","Evolutionary biology","Demography","Allele frequency","Single-nucleotide polymorphism","Genotype","Gene","Anthropology"],"sdg_mappings":[],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-11T07:13:25.708124Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
