Twins TS13

This resource describes fundamental features of the immune system (frequency of leukocyte subpopulations, cell surface protein expression) in a large cohort of twins. An accompanying manuscript uses a complementary dataset (link to be provided) to describe the association between immunophenotypes and gene variants (based on single nucleotide polymorphisms (SNPs)). Conclusion: The study of immunophenotypes in the context of genome wide association studies can provide mechanistic information about genetic control of normal human immunity and disease.
