Heterotopia are nodules or clumps of misplaced neurons that did not move to the correct location in the brain during earlydevelopment. Heterotopia are common malformations of cortical development.
The more extensive the subcortical heterotopia, the greater the deficit; bilateral heterotopia are almost invariably associated with severe developmental delay or mental retardation. In general, band heterotopia are seen exclusively in women; men with a mutation of the related gene (called XLIS or DCX ) usually die in utero or have a much more severe brain anomaly.
