Ancestry Informative Markers Clarify the Regional Admixture Variation in the Costa Rican Population
(Human Biology Open Access Pre-Prints. Paper 34., 2013-10-09)
Study for the first time a random sample from all regions of the country with AIMS (Ancestry Informative Markers) to address the individual and regional admixture proportions. A sample of 160 male individuals was screened ...
Aspectos ecológicos del cáncer gástrico en Costa Rica
(Revista de Biología Tropical 31(1) p.11-18, 1983-07-18)
An analysis of 1315 cases of gastric cancer from the records of the Ministry of Public Health, San
Jose, Costa Rica between 1977 and 1980 showed important geographical differences in the incidence, and
especially in ...
High mitochondrial mutation rates estimated from deep-rooting Costa Rican pedigrees
(American Journal of Physical Anthropology 2012 July ; 148(3): 327–333., 2012-07)
Estimates of mutation rates for the noncoding hypervariable Region I (HVR-I) of mitochondrial
DNA (mtDNA) vary widely, depending on whether they are inferred from phylogenies (assuming
that molecular evolution is clock-like) ...
Lack of a BglII site at the 5’ region of the PGK 1 locus: a new variant discovered in two Chibchan Amerindian groups from Costa Rica
(1995)
A new 3.8-kb allele at the 5" region of the PGK 1 locus detected by the probe pSPT/PGK is reported. This variant was discovered in the Cabecar and Guaymi, two Chibchan Amerindian groups of Costa Rica. So far, a polymorphism ...
Gene admixture in the Costa Rican population
(Ann Hum Genet; 67 (1) p. 71-80, 2003)
The general population of Costa Rica has sometimes been considered to be the product of an amalgamation
of groups of diverse origin. To determine the magnitude of accumulated admixture since Spanish colonization,
11 ...
Migration and Genetic Infrastructure of the Central American Guaymi and Their Affinities With Other Tribal Groups
(American Journal of Phisical Antropology: 58 p.201-214, 1982-06)
New genetic data on 40 red cell enzymes, antigenic blood groups, and serum proteins representing 42 separate loci, are reported for two Guaymi communities in Southeastern Costa Rica. These two settlements, Limoncito and ...
La estructura poblacional de dos grupos indígenas Guaymí de Costa Rica
(Revista del Hospital Nacional de Niños 17(1y2):297-307, 1982)
Fue llevado a cabo un estudio biomédico en dos poblaciones guaymi del sur de Costa Rica, Limoncito y Abrojo, que incluye datos biodemográficos y genéticos. Ambas poblaciones presentan patrones de dispersión espacial ...
Direct screening of a mitochindrial DNA deletion valuable for Ameridian evolutionary research [resumen]
(1994)
A rapid, simple restriction isotyping method is described for the direct screening of a previously characterized Amerindian mitochondrial DNA (mtDNA) marker ;onsisting of a 6-bp "Huetar" deletion. In a sample of 31 maternally ...
Estudio biomédico de los amerindios en Costa Rica
(1985)
A partir de 1979 se realizó un programa de investigación biomédica en varias poblaciones amerindias de Costa Rica que incluye estudios demográficos, ecológicos, genéticos, epidemiológicos y de salud. Los datos demográficos ...
Distribution and Evolution of CTG Repeats at the Myotonin Protein Kinase Gene in Human Populations
(1996)
We have analyzed the CTG repeat length and the neighboring Alu insertion/deletion (+/-) polymorphism in DNA samples from 16 ethnically and geographically diverse human populations to understand the evolutionary dynamics ...
