Lynch Syndrome Integrative Epidemiology and Genetics

The vision of the "Lynch syndrome INtegrative Epidemiology And GEnetics" (LINEAGE) Consortium is to collaboratively improve the lives and longevity of individuals and families with Lynch syndrome. The mission of the LINEAGE Consortium is to collaboratively improve Lynch syndrome care through high-quality research. This consortium will provide intellectual and infrastructure support to facilitate development of research questions, collection of standardized data and biospecimens, support of grant applications, and generation of collaborative manuscripts. Our aims are to: I. Establish a prospective cohort of individuals with Lynch syndrome II. Collect standardized longitudinal clinical and biosample data to elucidate Lynch Syndrome epidemiology and gene-host interactions III. Promote intervention trials to improve cancer prevention and early detection in Lynch Syndrome
