The Role of Genetic Polymorphisms in Innate Immune Response Genes in Susceptibility to Infections

The purpose of this study is to better understand genetic susceptibility to infections and the interactions of specific genetic polymorphisms of innate immune receptors with microbial and fungal organisms. The goals of this study are: 1. Find out if some people are more likely to get severe infections, than others. To do this we will compare patients with leukemia who develop severe infections to patients who do not develop infections. 2. Find out if some people are more likely to develop lymphoma than others. To do this we will compare patients with lymphoma to people without lymphoma who are of the same sex and similar age and ethnic background to the patients with lymphoma.
