Biosketch

Dr. Pollin is a human geneticist and board certified genetic counselor. Her current research program consists of three main areas: (1) using analytical tools to identify genes and genetic variants involved in susceptibility and response to treatment and preventive intervention for type 2 diabetes and related traits in the Amish, the Diabetes Prevention Program (DPP) and Treatment Options for Type 2 Diabetes in Adolescents and Youth (TODAY) Study; (2) elucidating the function of apolipoprotein C-III and cardioprotective and metabolic effects of its deficiency through deep phenotyping of carriers of the first known null mutation in the APOC3 gene which she discovered in 2008 (NIH R01 HL104193); and (3) integration of genomic medicine into health care.  In this latter area, she leads the Personalized Diabetes Medicine Program (PDMP), an NHGRI-funded (U01 HG007775) IGNITE (Implementing Genomics in Practice) Network Project designed to develop, disseminate and evaluate a sustainable approach to the detecting, genomically diagnosing and promoting individualized therapy for individuals with monogenic forms of diabetes and a cross-NHGRI payer/stakeholder engagement effort.  She co-leads the NICHD-funded (U24 HD093486) ClinGen Genomic Clinical Variant Expert Curation Panel for Monogenic Diabetes, which complements the PDMP in addressing the underdiagnosis of highly genetic forms of diabetes in which a molecular diagnosis is critical for receiving appropriate treatment.
