Marlo Gottfurcht Longstreet is the founder and president of the Tanner Project Foundation, which is in memory of her 11-year-old son, Tanner, who died of Glioblastoma in 2013. Tanner was also diagnosed with the mutant p53 gene, a hereditary cancer gene, which can lead to many types of cancers. The Foundation has funded several research projects for very early detection of cancer at the moment disease begins. The Tanner Project, at the J. Craig Venter Institute in La Jolla, California, develops personalized protocols that monitor patients who are predisposed to cancer. Marlo's 18-year-old daughter, Casey, carries the same mutant p53 gene and has an over 90% chance of developing cancer. Thankfully, Casey is healthy and has an awareness initiative on her Genome Generation website. Marlo and her family's story were featured on NBC Nightly News with Lester Holt, and she has been an inspirational and motivational speaker at several events and on cancer research videos. Marlo is currently publishing a book chronicling her journey.
