Mondo Description Microcephalic primordial dwarfism due to ZNF335 deficiency is characterized by severe antenatal microencephaly, simplified gyration, agenesis of the corpus callosum, absence of basal ganglia (very rare), pontocerebellar atrophy and involvement of the white matter with secondary cerebral atrophy. Congenital cataract, choanal atresia, multiple arthrogryposis and spastic tetraparesis can occur.

Uniprot Description A form of microcephaly, a disease defined as a head circumference more than 3 standard deviations below the age-related mean. Brain weight is markedly reduced and the cerebral cortex is disproportionately small. MCPH10 is characterized by extremely small head size and death usually by 1 year of age. Neuropathologic examination shows severe loss of neurons as well as neuronal loss of polarity and abnormal dendritic maturation.
