Assessment of genetic predisposition to lymphedema.

195 Background: In the United States, 203,000 women are diagnosed annually with breast cancer (BC). Currently, over 2.3 million women in the United States are breast cancer survivors. With the increased incidence and survivorship, more women are living with the long-term treatment effects such as lymphedema (LE). We are nearing completion of stage one of a three-stage research project to examine genetic factors that potentially predispose BC survivors to develop LE. In stage one, we are working to identify novel genetic polymorphisms pointing to genomic regions and genes associated with LE risk. In stage two, we will use exome sequencing to examine both rare and common genetic variants potentially associated with variation in symptom manifestations of LE in breast cancer survivors; to examine phenotypic and genotypic variation in LE emerging following cancer treatment; and to examine associations between LE phenotypes among breast cancer survivors with LE and genomic factors and non-genomic factors.
