Physical Physical characteristics of the syndrome can vary and are not universal. People with<unk>  often have a short skull (brachycephaly), thin lips, low-set and posterior-angled ears, and scalp alopecia above both ears. This bilateral scalp alopecia is the most consistent physical characteristic of<unk> . In addition to the shortness of the skull, it is also misshapen and often flattened on the back. Some people with<unk>  also have wide-set (hypertelorism) and crossed eyes (strabismus). Scarring or clouding of the cornea occurs in the majority of people with<unk> . A short stature is common. Neurological Aside from the physical characteristics of the eyes there is also less sensation in the eyes when stimulated. The eyes also show low motor control (ataxia). Along with ataxia comes a lack of coordination or ability to judge the distance of objects (dysmetria). MRIs show a constant feature of rhombencephalosynapsis–a condition marked by the absence or partial absence of the cerebellar vermis and varying degrees of fusion in the cerebellum in every case of<unk> . Also absent are the trigeminal nerve of the trigeminal cave and the foramen rotundum, causing abnormal sensations on the forehead and the corneas. One<unk>  case in Japan also presents fever-induced seizures. Others may or may not present with non-fever-induced seizures. Malformations of motor centers in the brain cause reduced muscle strength (hypotonia). Eleven of fifteen people in one study showed moderate-to-severe intellectual disability. In cases where it has been noted, head nodding is present. Hydrocephalus and enlargement of the ventricular system is consistently present. A reduced corpus callosum is present in some cases (agenesis of the corpus callosum). MRI showing fusion of cerebellar hemispheres common in GLH syndrome Behavioral<unk>  is associated with irritability, anxiety, insomnia, and self-harming behavior. Developmental disabilities often present as intellectual disability with social, occupational, and learning disabilities. Reduced eye sensation may cause self-harm to the eyes; one patient is on record as having put her fingers into her eyes to the point of causing additional corneal damage beyond what is normally characteristic of the syndrome.
