Epistasis: the key to understanding immunological disease?
Mitchison NA., Rose AM.
Epistasis is fast becoming central to the understanding of the complex relationship between genotype and phenotype observed in autoimmune disease. A study in this issue of the European Journal of Immunology uses in-depth analysis of genome-wide mapping by polymorphic microsatellite markers to shed light on the genomic control of autoimmunity and self-tolerance.
