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% in 100 Cubans patients. Conclusions: the polymorphism K832R was identified first in Cuba and it will make possible molecular studies by indirect methods.
