Microlissencephaly Norman-Roberts syndrome is also characterized by lissencephaly type 1 features with certain craniofacial abnormalities, such as a low, sloping forehead; abnormal prominence of the back portion of the head; a broad, prominent nasal bridge; and widely set eyes (ocular hyperterlorism). The most common cause of death among people with lissencephaly is aspiration (breathing in a foreign object, such as sucking food into your airway) and respiratory disease. [11] LIS1 mutation or deletion is not inherited from a parent and thus recurrence is unlikely. Of the genes that have been implicated in lissencephaly, DCX and ARX genes are notable because they are localized on the X chromosome. [12] DCX mutation causes the disorganisation of neocortical layering in the cerebral cortex leading to a reduced folding. Unfortunately, most cases of lissencephaly cant be prevented. Sometimes it can be difficult to distinguish between these conditions clinically so consultation with experts in lissencephaly is recommended to help ensure correct diagnosis and possible molecular testing.

But others develop normally with only mild learning differences. However, in cases of lissencephaly type 1, the cells fail to migrate to their destined locations resulting in neuronal dysmigration, and the cerebral cortex develops an insufficient number of cellular layers, with absence or incomplete development of gyri. If your healthcare provider suspects lissencephaly due to family history and/or the results of prenatal ultrasound, they may order specialized testing during pregnancy. It is early infection that leads to lissencephaly. [4] Other symptoms of the disorder may include unusual facial appearance, difficulty swallowing, and anomalies of the hands, fingers, or toes.
