Novel variations in the signal peptide region of transforming growth factor beta1 gene in patients with hepatitis: a brief report from India

Genotypic status of the signal peptide region of transforming growth factor beta1 (TGF-beta1) showed a significant difference in C/C-genotype frequency at +29 position (codon 10) between a range of viral hepatitis patients and controls (P = 0.009, OR = 3.15, CI = 1.29-7.678), contributed by those who were infected with hepatitis B virus (HBV) alone or HBV + hepatitis delta virus (HDV) (P = 0.003, OR = 5.0, CI = 1.78-13.97).
