Native Americans derive from a small number of Asian founders who likely arrived to the Americas via Beringia. However, additional details about intial colonization remain unclear. To investigate pioneering phase in we analyzed total 623 complete mtDNAs and Asia, including 20 new seven Asia. This sequence data was used direct high-resolution genotyping American 26 populations. Here describe more genetic diversity within founder population than previously reported. The newly resolved...
The large and diverse population of Latin America is potentially a powerful resource for elucidating the genetic basis complex traits through admixture mapping. However, no genome-wide characterization across has yet been attempted. Here, we report an analysis in thirteen Mestizo populations (i.e. regions mainly European Native settlement) from seven countries based on data 678 autosomal 29 X-chromosome microsatellites. We found extensive variation American ancestry (and generally low levels...
We analyzed 391 samples from 12 Argentinian populations the Center-West, East and North-West regions with Illumina Human Exome Beadchip v1.0 (HumanExome-12v1-A). did Principal Components analysis to infer patterns of populational divergence migrations. identified proportions European, African Native American ancestry found a correlation between distance Buenos Aires proportion ancestry, where highest corresponds Northernmost populations, which is also furthest capital. Most European sources...
Similarly to other populations across the Americas, Argentinean trace back their genetic ancestry into African, European and Native American ancestors, reflecting a complex demographic history with multiple migration admixture events in pre- post-colonial times. However, little is known about sub-continental origins of these three main ancestries. We present new high-throughput genotyping data for 87 admixed individuals Argentina. This was combined previously published region then compared...
To confirm the geographic and ethnic segregation of HTLV-I HTLV-II carriers in native populations South America, we have conducted a seroepidemiological study including distributed among seven groups Andes highlands Colombia, Peru, Bolivia, Argentina, Chile, two on Chiloe Island Easter Island; lowlands along Atlantic coast Orinoco, Amazon, Patagonia, one group Island. The incidence rate HTLVII varied groups, ranging from 0.8 to 6.8% for seropositivity 1.4 57.9% seropositivity. A new focus...
Abstract We analyzed 21 paragroup Q* Y chromosomes from South American aboriginal and urban populations. Our aims were to evaluate the phylogenetic status, geographic distribution, genetic diversity in these groups of compare degree variation relation Q1a3a haplotypes. All our series five samples North presented derivate state for M346, that is present upstream M3, determined Q1a3* paragroup. found a restrictive distribution low frequency America. assumed this could be reflecting extreme...
In order to study the isonymic structure of Argentina, surname distributions 22.6 million electors registered for year 2001 were analyzed in 24 districts (distritos) and 541 municipalities (municipios) country. The number different surnames found was 414,441. Matrices distances between constructed tested correlation with geographic distance capital towns districts. We that, whole Euclidean correlated log (r=0.480+/- 0.067). A dendrogram regions built from matrix distances, using UPGMA...
Autosomal recessive (AR) complete IRF8 deficiency is a rare severe inborn error of immunity underlying an absence blood myeloid mononuclear cells, intracerebral calcifications, and multiple infections. Only three unrelated patients have been reported.We studied Argentinian child with infectious diseases pulmonary alveolar proteinosis (PAP). We performed whole-exome sequencing (WES) characterized his condition by genetic, immunological, clinical means.The patient was born lived in Argentina....
An increase in the prevalence of obesity due to lockdown and confinement linked COVID-19 is observed. Variations nutritional status schoolchildren from Jujuy are analyzed relation (2019-2021) its relationship with socio-demographic variables school environment. This an observational, descriptive study. Data 56,695 aged 6-18 years old based on two temporary cuts (2019 pre-confinement 2021 post-confinement). The (underweight, overweight, obese) was established using IOTF (International Obesity...
This study corresponds to the first large-scale genetic analysis of inherited eye diseases (IED) in Argentina and describes comprehensive profile a large cohort patients. Medical records 22 ophthalmology genetics services throughout 13 Argentinian provinces were analyzed retrospectively. Patients with clinical diagnosis an ophthalmic disease history testing included. Medical, ophthalmological family was collected. A total 773 patients from 637 families included, 98% having retinal disease....
In Bolivia, the Hispanic dual surname system is used. To describe isonymic structure of distribution 12,139,448 persons registered in 2006 census data was studied 9 districts and 112 provinces nation, for a total 23,244,064 surnames. The number different surnames found 174,922. Matrices distances between administrative units (districts provinces) were constructed tested correlation with geographic distance. provinces, correlated distance (r = 0.545 ± 0.011 Euclidean, 0.501 0.012 Nei's, 0.556...
Background: Highland child populations show low growth rates.Aim: To evaluate the variation of size, mass and body surface area Jujenean infants (1–4 years) as a function geographic altitude.Subjects methods: Nutritional status 8059 healthy was determined based on weight height data; index, ponderal area, area/mass ectomorphy were calculated. Variables standardized with provincial mean WHO references. Data grouped by age, sex altitude: Highlands (≥2500 masl) Lowlands (<2500 masl)....
The settlement of the Americas has been focus incessant debate for more than 100 years, and open questions regarding timing spatial patterns colonization still remain today. Phylogenetic studies with complete human Y chromosome sequences are used as a highly informative tool to investigate history populations in given time frame. To study phylogenetic relationships Native American lineages infer Americas, we analyzed Q Haplogroup, which is Pan-American haplogroup represents practically all...
To analyze the trend and spatial distribution of infant mortality from congenital malformations in Argentina between 2002 2006.Data were provided by Ministry Public Health. Congenital classified according to International Classification Diseases, 10th revision. Early neonatal, late neonatal postneonatal components, subgroups specific estimated departments, provinces, regions determine: a) malformations- related death rate; b) rate due malformations. Both indicators correlated with respective...
The isonymy structure of Buenos Aires was studied based on its surname frequency. Information 2,552,359 voters the 28 districts used to estimate Lasker's coefficient relationship by (Ri), diversity according Fisher's a, consanguinity resulting from random (F), and Nei's, Euclidean distances. These distances were correlated with geographic distances, which calculated assigning an arbitrary point each district measuring a map city. Ri × 105 F 104 averages located south Rivadavia Avenue higher...
In order to describe the isonymic structure of Paraguay, distribution 4,843,868 surnames 2,882,163 persons was studied in 18 departments and 237 districts nation.
