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.
Andermann syndrome, also known as agenesis of corpus callosum with neuronopathy (ACCPN), Charlevoix disease and KCC3 axonopathy among other names, [1] is a very rare neurodegenerative genetic disorder that damages the nerves used to control muscles and related to sensation and is often associated with agenesis of the corpus callosum. [1] [2] [3 ...
Partial or complete absence of the corpus callosum in the brain (agenesis of the corpus callosum); Eye abnormalities known as "lacunae" of the retina that are quite specific to this disorder; optic nerve coloboma; and; The development in infancy of seizures that are called infantile spasms.
When the corpus callosum is missing or not formed properly, it can lead to many dysfunctions throughout the body including hypothermia and hyperhidrosis. [4] Agenesis of the corpus callosum has been found in 40% of Shapiro syndrome cases reported. [4] It is theorized that Shapiro syndrome develops based on genetic factors. [1]
Agenesis of the corpus callosum (ACC) is a rare congenital disorder that is one of the most common brain malformations observed in human beings, [30] in which the corpus callosum is partially or completely absent. ACC is usually diagnosed within the first two years of life, and may manifest as a severe syndrome in infancy or childhood, as a ...
This happens as a result of partial or complete absence of the corpus callosum. Corpus callosum is the band of white matter connecting the two cerebral hemispheres. The corpus callosum plays an extremely important role in interhemispheric communication, thus lack of or absence of these neural fibers results in a number of disabilities. [12]
Vici syndrome, also called immunodeficiency with cleft lip/palate, cataract, hypopigmentation and absent corpus callosum (or absent corpus callosum cataract immunodeficiency), [1] is a rare autosomal recessive [2] congenital disorder characterized by albinism, agenesis of the corpus callosum, cataracts, cardiomyopathy, severe psychomotor retardation, seizures, immunodeficiency and recurrent ...
The males (all infants) had partial corpus callosum agenesis, severe intellectual disabilities, developmental delays, and epilepsy. The disorder first manifested right after birth, with recurrent seizures occurring hours after it. Out of these 5 babies, 3 had died. Post-mortem examination of one of the dead infants revealed chemical and ...
