The nucleotide sequence variations as well as the amino acid changes in the sequenced part of the carboxyl-terminus (codons 431–540) of the EBNA1 gene are shown. Numbers across the top correspond to t
ABSTRACT Objective: to compare the polymorphism of the Glutathione S-transferase theta 1 (GSTT1) and Glutathione S-transferase mu 1 (GSTM1) genes from the tumor area with the proximal and distal margi
