ABSTRACT

OBJETIVO: Determinar la relación del polimorfismo TaqI del gen del receptor de la vitamina D (RVD) con la lepra lepromatosa (LL) en individuos originarios de Sinaloa, México. MATERIAL Y MÉTODOS: Se amplificó un fragmento de 740 pb del gen RVD en muestras de ADN de 71 pacientes con LL y 144 controles en el Hospital General de Culiacán durante el periodo 2004-2007. El polimorfismo se identificó mediante la endonucleasa TaqI. RESULTADOS: Se observó un aumento de relevancia estadística del genotipo TT en pacientes con LL en comparación con los controles (p= 0.040; RM= 1.82). CONCLUSIÓN: Se demuestra un nexo entre el genotipo TT y la susceptibilidad a la LL.


OBJETIVE: To establish the association of the vitamin D receptor gene TaqI polymorphism with lepromatous leprosy (LL) in individuals from Sinaloa, Mexico. MATERIAL AND METHODS: A 740 bp fragment was amplified from the VDR gene in DNA samples of 71 patients with LL and 144 controls in the Hospital General de Culiacán during 2004-2007. Polymorphism was identified through TaqI endonuclease. RESULTS: A significant increase in the genotype TT of the VDR gene was observed in patients when compared to controls (p = 0.040; OR = 1.82). CONCLUSIONS: Our data support the association between the TT genotype and susceptibility to LL in this Mexican population.
