Dysplasia and dysgenesis of the corpus callosum are nonspecific descriptions that imply defective development of the corpus callosum. The term dysplasia is applied when the morphology of the corpus callosum is altered as a congenital trait. For instance, the corpus callosum may be hump-shaped, kinked, or a striped corpus callosum that lacks an anatomically distinct genu and splenium. The phenotype is HP_0006989 (Dysplastic corpus callosum). Also known as: Dysgenesis of corpus callosum, Dysplasia of corpus callosum.
