Genetic Structure Analysis of Three Hispanic Populations from Costa Rica, Mexico, and the Southwestern United States Using Y-Chromosome STR Markers and mtDNA Sequences
(Human Biology, October 2006, v. 78, no. 5, pp. 551–563., 2006)
Two hundred seventeen male subjects from Costa Rica, Mexico,
and the Hispanic population of the southwestern United States were
studied. Twelve Y-chromosome STRs and the HVSI sequence of the mtDNA
were analyzed to ...
Helicobacter pylori in a Costa Rican dyspeptic patient population
(1994-03)
Gastric biopsies from 65 Costa Rican dyspeptic patients were investigated for the presence ofHelicobacter pylori DNA by polymerase chain reaction (PCR) amplification of 16S rRNA sequences. Both frozen and paraffin-embedded ...
Charcot-Marie-Tooth disease: a novel Tyr145Ser mutation in the myelin protein zero (MPZ, P0) gene causes different phenotypes in homozygous and heterozygous carriers within one family
(Neurogenetics : 4 (4) p. 191-197, 2003-07-05)
Abstract. Charcot-Marie-Tooth disease type IB (CMT 1B) is caused by mutations in the gene
coding for peripheral myelin protein zero (MPZ, P0) that plays a fundamental role in adhesion
and compaction of peripheral myelin. ...
A novel myosin heavy chain gene in human chromosome 19q13.3
(Gene: 312 p. 165-171, 2003-07)
A human myosin heavy chain gene was identified in chromosome 19q13 by computational sequence analysis, RT-PCR and DNA
sequencing of the cDNA. The complete cDNA has a length of 6786 bp and comprises 41 exons (40 coding) ...
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 ...
Blood Group, Red Cell, and Serum Protein Variation in the Cabecar and Huetar, Two Chibchan Amerindian Tribes of Costa Rica
(American Journal Human Biology ;13 (1): p. 57-64, 2001)
Genetic variation, using blood groups and red cell and serum proteins, was surveyed in the Cabecar of Chirripo and the Huetar of Quitirrisi, Costa Rica. Thirty-nine loci were screened in a sample of 91 Cabecars and 40 loci ...
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 ...
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 ...
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 ...
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 ...
