We are collaborating on a number of international pooled analyses being conducted under the auspices of the International Lymphoma Epidemiology Consortium (InterLymph). We have provided epidemiological data and germline DNA on people with and without non-Hodgkin lymphoma to help interrogate the environmental and genetic risk factors for non-Hodgkin lymphoma and the more prevalent lymphoma subtypes. We are also leading an analysis of sun exposure by genotype interactions and non-Hodgkin lymphoma risk.
