Caudal regression syndrome is a disorder that impairs the development of the lower caudal half of the body. Affected areas can include the lower back and limbs, the genitourinary tract , and the gastrointestinal tract. In this disorder, the bones of the lower spine vertebrae are frequently misshapen or missing, and the corresponding sections of the spinal cord are also irregular or missing. Affected individuals may have incomplete closure of the vertebrae around the spinal cord, a fluid-filled sac on the back covered by skin that may or may not contain part of the spinal cord, or tufts of hair at the base of the spine. People with caudal regression syndrome can also have an abnormal side-to-side curvature of the spine scoliosis. The spinal abnormalities may affect the size and shape of the chest, leading to breathing problems in some individuals.

Agenesis of the corpus callosum ACC is a rare birth defect in which there is a complete or partial absence of the corpus callosum. It occurs when the development of the corpus callosum, the band of white matter connecting the two hemispheres in the brain , in the embryo is disrupted. The result of this is that the fibers that would otherwise form the corpus callosum are instead longitudinally oriented along the ipsilateral ventricular wall and form structures called Probst bundles. In addition to agenesis, other degrees of callosal defects exist, including hypoplasia underdevelopment or thinness , hypogenesis partial agenesis or dysgenesis malformation.
