The influence of the APOE gene and Traumatic Brain Injury on the frequency of LOAD Lead Investigator: Chesney Romer Institution : Columbia High School E-Mail : 20romerch1@egcsd.org Proposal ID : 1236 Proposal Description: To correlate incidence of TBI together with the presence of APOE alleles to the onset of LOAD. My area of focus for my project is to study data files to ascertain a correlation between the severity of a traumatic brain injury, the genetic possession of the APOE e4 allele, and the age of onset of LOAD. I intend to use the data file from the NACC database and the statistics program "Minitab."
