Polymorphisms of BIRC5 Gene is Associated with Chronic HBV Infection in Iranian Population.

Survivin can affect the progression of infection and is considered as a marker of various malignancies. The aim of the study was to investigate the possible association of gene polymorphisms of survivin (-1547A/G, -644C/T, -625 C/G, -241C/T, -31G/C, -141G/C) and chronic hepatitis B infection in Iranian patients. The genotypes of survivin SNPs were investigated by polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) method using 100 chronic HBV infected patients (HBV), 40 spontaneously recovered HBV subjects and 100 healthy controls (C). Serum level of survivin was determined using ELISA method. The -1547G, -625C, -241T and -31C alleles were associated with increased susceptibility to chronic hepatitis B infection (P = 0.001, P < 0.001, P = 0.003 and P < 0.001 respectively). Chronic HBV patients with -625CC, -241TT and -31CC genotypes had higher levels of survvin. Survivin -1547A/G, -625 C/G, -241C/T and -31G/C gene polymorphisms may be associated with chronic HBV susceptibility in Iranian HBV patients. © Association of Clinical Biochemists of India 2019.
