Fig. 1From: Cytotoxic T-lymphocyte antigen-4 +49A/G polymorphisms in Sudanese adults with type 1 diabetes and latent autoimmune diabetesPCR-RFLP analysis for CTLA-4 +49A/G polymorphism. Two fragments of 74/88 bp indicate homozygous (G/G), three fragments of 74, 88 and 162 bp indicate heterozygous genotype (A/G) and undigested fragment of 162 bp indicate homozygous A/A genotype.
