Scrabble?! DYSGENESES

Definitions of DYSGENESES in various dictionaries:

Agenesis of the corpus callosum (ACC) is a rare birth defect (congenital disorder) in which there is a complete or partial absence of the corpus callosum. It occurs when the corpus callosum, the band of white matter connecting the two hemispheres in the brain, fails to develop normally, typically during pregnancy. The fibers that would otherwise form the corpus callosum become longitudinally oriented along the ipsilateral ventricular wall and form structures called Probst bundles. In addition to agenesis of the corpus callosum, other callosal disorders include hypogenesis (partial agenesis, usually referring to the length), dysgenesis (malformation) and hypoplasia (underdevelopment, usually referring to the thickness) of the corpus callosum.
