1. Interethnic admixture and the evolution of Latin American populations
A general introduction to the origins and history of Latin American populations is followed by a systematic review of the data from molecular autosomal assessments of the ethnic/continental (European, African, Amerindian) ancestries for 24 Latin American countries or territories. The data surveyed are of varying quality but provide a general picture of the p

2. Reconstruction of major maternal and paternal lineages of the Cape Muslim population
The earliest Cape Muslims were brought to the Cape (Cape Town -South Africa) from Africa and Asia from 1652 to 1834. They were part of an involuntary migration of slaves, political prisoners and convicts, and they contributed to the ethnic diversity of the present Cape Muslim population of South Africa. The history of the Cape Muslims has been well documente

3. Association of serum lipid components and obesity with genetic ancestry in an admixed population of elderly women
The prevalence of metabolic disorders varies among ethnic populations and these disorders represent a critical health care issue for elderly women. This study investigated the correlation between genetic ancestry and body composition, metabolic traits and clinical status in a sample of elderly women. Clinical, nutritional and anthropometric data were collect

4. Influência de polimorfismos em genes de metabolismo de xenobióticos e reparação de DNA no risco ocupacional de mineiros de carvão a céu aberto
Colombia has one of the world s largest coal reserves being the fifth biggest thermal coal exporter world-wide. In open-cast coal mining extraction, large amounts of dust particles and heavy metals are released into the atmosphere, where they can form complex mixtures, representing a significant health risks to occupationally exposed workers. In addition, in

5. Genetics, surnames, grandparents' nationalities, and ethnic admixture in southern Brazil - do the patterns of variation coincide?
Uma amostra de 2.708 descendentes de europeus que vivem no Rio Grande do Sul, o qual foi subdividido em sete mesorregiões, e de 226 pessoas da mesma procedência provenientes de Santa Catarina foi estudada quanto a 17 sistemas genéticos protéicos, nacionalidades dos avós, sobrenomes dos indivíduos e mistura interétnica. Não foram encontradas diferenç

6. Marcadores Genéticos de Ancestralidade em Comunidades Fundadas por Açorianos na Ilha de Santa Catarina / Ancestry Informative Markers in Partially Isolated Communities Founded by Azoreans in the Santa Catarina Island
As comunidades da Costa da Lagoa (CL) e São João do Rio Vermelho (RV) estão localizadas na Ilha de Santa Catarina, Sul do Brasil, e foram colonizadas na segunda metade do século XVIII por imigrantes vindos do Arquipélago de Açores. Estudos demográficos e genéticos mostraram também a presença de componentes africanos e ameríndios. CL é considerada

7. Impacto da miscigenaÃÃo na aplicaÃÃo do HapMap para a populaÃÃo brasileira avaliados nos genes PTPN22 e VDR
The PTPN22 and VDR genes are commonly associated to several autoimmune diseases and complex phenotypes related to bone metabolism. The association of some of those polymorphisms are ethnic-specific, and therefore, admixture population studies must be conditionally evaluated to these factors. The Brazilian population is considered the most heterogeneous in th

8. Dinâmica da Mistura Étnica em Comunidades Remanescentes de Quilombo Brasileiras / Inter-Ethnic Admixture Dynamics in Brazilian Quilombo Remnant Communities
Apesar da intensa mistura étnica na formação da população Brasileira, pequenos grupos isolados ainda podem ser encontrados, principalmente representados pelas tribos indígenas e comunidades remanescentes de quilombo. As comunidades de Barra (BA), São Gonçalo (BA) e Valongo (SC) apresentam diferentes histórias demográficas de formação. Os AIMs (Ma

9. Y-STR diversity and ethnic admixture in White and Mulatto Brazilian population samples
We investigated 50 Mulatto and 120 White Brazilians for the Y-chromosome short tandem repeat (Y-STR) markers (DYS19, DYS390, DYS391, DYS392 and DYS393) and found 79 different haplotypes in the White and 35 in the Mulatto sample. Admixture estimates based on allele frequencies showed that the admixture of the white sample was 89% European, 6% African and 5% A

10. Microsatellite studies on an isolated population of African descent in the Brazilian state of Bahia
The African descent population of the Bananal community in the Brazilian state of Bahia (BA) was characterized as a genetic isolate and analyzed for some short tandem repeat (STR) microsatellite autosomic polymorphic loci (CSF1PO, TH01, TPOX, F13A1, FESFPS and vWA). These genetic variants were further compared to data obtained from an urban sample from the t

11. Prevalence of deltaF508, G551D, G542X, and R553X mutations among cystic fibrosis patients in the North of Brazil
Cystic fibrosis (CF) is the most common genetic disease among Caucasians and is rare among sub-Saharan Africans. The Brazilian population is not ethnically homogeneous but it is the result of three-way ethnic admixture of Europeans, Africans and Amerindians in varying proportions, depending on the region. In the present study, we investigated 33 patients who

12. Ethnicity and glutathione S-transferase (GSTM1/GSTT1) polymorphisms in a Brazilian population
The distribution of polymorphisms related to glutathione S-transferases (GST) has been described in different populations, mainly for white individuals. We evaluated the distribution of GST mu (GSTM1) and theta (GSTT1) genotypes in 594 individuals, by multiplex PCR-based methods, using amplification of the exon 7 of CYP1A1 gene as an internal control. In Sã
