Molecular phylogenetic inference of the howler monkey radiation (Primates
The first five-year evaluation of cystic fibrosis neonatal screening program in São Paulo State, Brazil
The Hospital of the Ribeirão Preto Medical School, University of São Paulo is one of the three screening centers in São Paulo State, Brazil, and has included a test for cystic fibrosis (CF) since February 6, 2010, by a court order. We evaluated the first five years of this CF-newborn screening program. The original immunoreactive trypsinogen (IRT)/IRT screening protocol was adopted in Brazil. A total of 173,571 newborns were screened, 1,922 (1.1%…
The interaction of cultural consonance and a polymorphism in the 2A serotonin receptor in relation to depression in Brazil
OBJECTIVES: To replicate a previously identified gene-environment interaction between a genetic polymorphism in the serotonin 2A receptor and cultural consonance in family life in relation to depressive symptoms (Dressler et al., 2009). METHODS: A sample of 402 individuals in a sample drawn from four different economic strata in Ribeirão Preto, Brazil was interviewed and genotyped. RESULTS: Cultural consonance in family life has an inverse associ…

Who were the male founders of rural Brazilian Afro-derived communities? A proposal based on three populations
This observation suggested an admixture process that has occurred over generations and directional mating between European males and African female slaves that must have occurred on farms before the slaves escaped. This means that the admixture occurred before the slaves escaped and the foundation of the quilombo

Distribution of Hemoglobin Phenotypes in Four Different Districts of Porto Velho, Rondônia, Brazil
Hemoglobin profile studies have been carried out in four samples from different districts of Porto Velho (Rondônia State) in the western Amazonian region of Brazil: Candelária, Bate Estaca, Hemeron (at the State Blood Bank), and São Carlos. Samples from 337 unrelated individuals were collected during medical and paramedical team visits by professionals from the Instituto de Pesquisa em Patologia Tropical and the Centro de Pesquisa em Patologias T…

MtDNA Haplogroup Analysis of Black Brazilian and Sub-Saharan Populations
Seventy individuals from two African and four black Brazilian populations were studied for the first hypervariable segment of mtDNA. To delineate a more complete phylogeographic scenario of the African mtDNA haplogroups in Brazil and to provide additional information on the nature of the Atlantic slave trade, we analyzed our data together with previously published data. The results indicate different sources of African slaves for the four major B…
Demographic and evolutionary trajectories of the Guarani and Kaingang natives of Brazil
A total of 278 individuals from two Brazilian Indian tribes (Guarani and Kaingang) living in five different localities had their mitochondrial DNA sequenced for the first hypervariable segment (HVS-I), and a fraction of them was also studied for seven biallelic Y-chromosome polymorphisms. Nineteen HVS-I lineages were detected, which showed distinct distributions in the two tribes. The G ST value obtained with the mtDNA data is about 5 times highe…
Heterogeneity of the genome ancestry of individuals classified as White in the State of Rio Grande do Sul, Brazil
One hundred nineteen individuals classified as White, living in different localities of the Brazilian state of Rio Grande do Sul, were studied in relation to the HVS-I region of the mitochondrial DNA (mtDNA). The male fraction of the sample (N = 74) was also tested for seven Y-chromosome polymorphisms. In a specific population (Veranópolis), a city characterized by a large influence of the Italian immigration of the 19th century, the results from…

Heterogeneity of the Y Chromosome in Afro-Brazilian Populations
Sixteen biallelic markers (SRY10831a, SRY10831b, SRY4064, SRY2627, 92R7, P2, P3, M34, M9, M3, M2, YAP, M60, M89, M213, M216) located in the nonrecombinant region of the Y chromosome were analyzed in 209 individuals belonging to six Brazilian populations: four Afro-Brazilian populations, one population of white European descendants, and one population of Japanese descendants. The results showed that most of the Y chromosomes of the Afro-Brazilians…
Genetic diversity of two African and sixteen South American populations determined on the basis of six hypervariable loci
A total of 582 individuals (1,164 chromosomes) from two African, eight African-derived South American, five South American Amerindian, and three Brazilian urban populations were studied at four variable number of tandem repeat (VNTR) and two short tandem repeat (STR) hypervariable loci. These two sets of loci did not show distinct allele profiles, which might be expected if different processes promoted their molecular differentiation. The two Afr…
Genetic variability in two Brazilian ethnic groups
Sequence data from the first hypervariable segment of the mitochondrial DNA control region of 124 subjects belonging to three African-Brazilian and three Brazilian Indian populations were compared with information related to 12 protein genetic loci from 601 persons living in the same localities. There is high diversity among the mtDNA sites, and the most variable in one ethnic group are not the most variable in the other. No differences in gene d…
