Maria Luisa Guerrera, MD, is a hematologist, an Instructor of Medicine at Harvard Medical School, and a recipient of the Robert A. Kyle Career Development Award from the International Waldenström’s Macroglobulinemia Foundation. Dr. Guerrera is studying the genomic events that are responsible for WM disease progression following acquisition of the MYD88 mutation. Her work, which was recently reported in an oral presentation at the 64th Annual Meeting of the American Society of Hematology, identified the WNK2 gene as a major enabler of WM disease formation by impacting the ERK signaling network.
