RESUMO

AIM: The present review was aimed at analyzing the pharmacogenetic scientific activity in Central America and the Caribbean. MATERIALS & METHODS: A literature search for pharmacogenetic studies in each country of the region was conducted on three databases using a list of the most relevant pharmacogenetic biomarkers including 'phenotyping probe drugs' for major drug metabolizing enzymes. The review included 132 papers involving 47 biomarkers and 35,079 subjects (11,129 healthy volunteers and 23,950 patients). RESULTS: The country with the most intensive pharmacogenetic research was Costa Rica. The most studied medical therapeutic area was oncology, and the most investigated biomarkers were CYP2D6 and HLA-A/B. Conclusion: Research activity on pharmacogenetics in Central American and the Caribbean populations is limited or absent. Therefore, strategies to promote effective collaborations, and foster interregional initiatives and research efforts among countries from the region could help for the rational clinical implementation of pharmacogenetics and personalized medicine.

RESUMO

Introducción: la enfermedad de Wilson se caracteriza por la acumulación de cobre fundamentalmente en el hígado. Se transmite con un patrón de herencia autosómico recesivo. La causa molecular que la provoca son las mutaciones en el gen atp7b. Se han informado en la literatura varios polimorfismos en el gen atp7b. Objetivo: identificar el polimorfismo K832R en 100 pacientes cubanos diagnosticados clínicamente con la Enfermedad de Wilson. Material y Métodos: en el presente estudio se empleó la técnica de cribaje: Polimorfismo Conformacional de Simple Cadena para la determinación de cambios conformacionales en el exón 10. Se utilizó la Técnica de Secuenciación para la identificación del polimorfismo K832R. Resultados: se detectaron tres cambios conformacionales diferentes denominados: a, b y c. El cambio conformacional b y c correspondió al polimorfismo K832R en estado heterocigótico y homocigótico respectivamente. La frecuencia alélica del polimorfismo K832R en 100 pacientes cubanos diagnosticados clínicamente con la Enfermedad de Wilson es de 35 por ciento. Conclusiones: se identificó por primera vez en Cuba el polimorfismo K832R y posibilitará hacer estudios moleculares por métodos indirectos(AU)


ABSTRACT Introduction: Wilson's disease is characterized by accumulation of copper in liver, brain and cornea. It is an autosomal recessive inherited disorder of copper metabolism. The molecular causes are mutations in the atp7b gene. It has been reported in the literature several polymorphisms in the atp7b gene. Objective: this research aims to identify the polymorphism K832R in 100 Cubans patients with clinical diagnosis of Wilson's disease. Materials and Methods: in this study we used the technique of screening: single stranded conformational polymorphism for the determination of conformational shifts in exon 10. We used sequencing technique for identifying the K832R polymorphism. Results: they identified three different conformational shifts denominated: a, b and c. The shifts b and c corresponded to polymorphism K832R in heterozygous and homozygous state respectively. The frequency of this polymorphism K832R is 35 percent in 100 Cubans patients. Conclusions: the polymorphism K832R was identified first in Cuba and it will make possible molecular studies by indirect methods(AU)
