Biochemistry

Magnetic resonance imaging (MRI) scans of the brain in three children with a missing copy of the Chaserr gene. The scans performed at age 8 months or 4 years (top row) reveal structural changes in the brain, including reduced volume of the brain stem (asterisks) and decreased myelin coating of nerves (arrows) in deep-seated brain areas. These changes are less apparent at 1 month of age (bottom row)
