Analysis of the -398C/T polymorphism in the perforin gene in oncohematological patients

BACKGROUND: Recently, single nucleotide polymorphisms (SNPs) were identified in the promoter region of the perforin gene (PRF1) and it was found that the -398T mutant allele is correlated with lower amounts of protein in circulating CD8+ cytotoxic T lymphocytes. OBJECTIVE: The aim of this study was to investigate the presence of the -398C/T polymorphism in the perforin gene in oncohematological patients. Methods: Sixty-two patients with hematological malignancies treated at the teaching hospital of the Universidade Federal do Triângulo Mineiro were invited to participate in this study. The id...
