Knickmeyer, PhD, lead author of the study and assistant professor of psychiatry in the University of North Carolina School of Medicine. The study was published online by the journal <em>Cerebral Cortex<\/em> on Jan. 3, 2013.<\/p>\n<p><strong>The study included 272 infants who received MRI scans at UNC Hospitals shortly after birth<\/strong>. The DNA of each was tested for 10 common variations in 7 genes that have been linked to brain structure in adults. These genes have also been implicated in conditions such as schizophrenia, bipolar disorder, autism, Alzheimer\u2019s disease, anxiety disorders and depression.<\/p>\n<p><strong>For some polymorphisms \u2013 such as a variation in the APOE gene which is associated with Alzheimer\u2019s disease \u2013 the brain changes in infants looked very similar to brain changes found in adults with the same variants<\/strong>, Knickmeyer said. \u201cThis could stimulate an exciting new line of research focused on preventing onset of illness through very early intervention in at-risk individuals.\u201d<\/p>\n<p><strong>But this was not true for every polymorphism included in the study<\/strong>, said John H. Gilmore, MD, senior author of the study and Thad &amp; Alice Eure Distinguished Professor and Vice Chair for Research and Scientific Affairs in the UNC Department of Psychiatry.<\/p>\n<p>For example, the study included two variants in the DISC1 gene. <strong>For one of these variants, known as rs821616, the infant brains looked very similar to the brains of adults with this variant<\/strong>. But there was no such similarity between infant brains and adult brains for the other variant, rs6675281.<\/p>\n<p>\u201cThis suggests that <strong>the brain changes associated with this gene variant aren\u2019t present at birth but develop later in life, perhaps during puberty<\/strong>,\u201d Gilmore said.<\/p>\n<p>\u201cIt\u2019s fascinating that different variants in the same gene have such unique effects in terms of when they affect brain development,\u201d said Knickmeyer.<\/p><\/blockquote>\n<p>In addition to Knickmeyer and Gilmore, authors of the study were Jiaping Wang, PhD; Hongtu Zhu, PhD; Xiujuan Geng, PhD; Sandra Woolson, MPh;\u00a0 Robert M. Hamer, PhD; Thomas Konneker, BA; Weili Lin, PhD; and Martin Styner, PhD.
