A rare, genetic form of pontocerebellar hypoplasia characterized by pontocerebellar hypoplasia and progressive neocortical atrophy that manifests clinically with uncoordinated sucking and swallowing, and generalized clonus in the neonate. In early childhood, spasticity, chorea/dyskinesia, seizures and progressive microcephaly develop. Voluntary motor development is lacking.

Pontocerebellar hypoplasia type 7 (PCH7) is a novel very rare form of pontocerebellar hypoplasia with unknown etiology and poor prognosis reported in four patients and is characterized clinically during the neonatal period by hypotonia, no palpable gonads, micropenis and from infancy by progressive microcephaly, apneic episodes, poor feeding, seizures and regression of penis. MRI demonstrates a pontocerebellar hypoplasia. PCH7 is expressed as PCH with 46,XY disorder of sex development in individuals with XY karyotype, and may be expressed as PCH only in individuals with XX karyotype.

A rare, genetic form of pontocerebellar hypoplasia (PCH) characterized by neocortical and pontocerebellar hypoplasia with pons and cerebellum equally affected and that clinically manifests with neonatal hypotonia and impaired swallowing followed by seizures, optic atrophy and short stature from infancy onward. Movement disorders, as seen in other forms of PCH, are absent.	Finding site	False	Pontine structure	Inferred relationship	Some	2
A severe, genetic form of pontocerebellar hypoplasia (PCH) characterized by spinal cord anterior horn cell degeneration in addition to pontocerebellar hypoplasia.

Pontocerebellar hypoplasia type 8 (PCH8) is a novel very rare form of pontocerebellar hypoplasia characterized clinically by progressive microencephaly, feeding difficulties, severe developmental delay, although walking may be achieved, hypotonia often associated with increased muscle tone of lower extremities and deep tendon reflexes, joint deformities in the lower extremities, and occasionally complex seizures. PCH8 is caused by a loss-of-function mutation in the CHMP1A gene. MRI demonstrates a pontocerebellar hypoplasia with vermis and hemispheres equally affected and mild to severely reduced cerebral white matter volume with a fully formed very thin corpus callosum.

A rare genetic subtype of non-syndromic pontocerebellar hypoplasia with characteristics of progressive cerebellum and brainstem atrophy, corpus callosum hypo/aplasia and progressive post-natal microcephaly. Patients typically present profound global developmental delay, spastic tetraparesis, seizures, cortical visual impairment and on neuroimaging abnormal brain morphology that includes pontocerebellar hypoplasia, figure of 8 midbrain appearance and more variably interhemispheric cysts, ventriculomegaly and cerebral dysmyelination.

A rare genetic pontocerebellar hypoplasia subtype with characteristics of severe psychomotor developmental delay, progressive microcephaly, progressive spasticity, seizures and brain abnormalities consisting of mild atrophy of the cerebellum, pons and corpus callosum and cortical atrophy with delayed myelination. Patients may present dysmorphic facial features (high arched eyebrows, prominent eyes, long palpebral fissures and eyelashes, broad nasal root and hypoplastic alae nasi) and an axonal sensorimotor neuropathy.

A rare genetic non-syndromic cerebral malformation due to abnormal neuronal migration disease with the association of cortical dysplasia and pontocerebellar hypoplasia, manifesting with global developmental delay, mild to severe intellectual disability, axial hypotonia, strabismus, nystagmus and occasionally, optic nerve hypoplasia. Brain imaging reveals variable malformations, including frontally predominant microgyria, gyral disorganization and simplification, dysmorphic and hypertrophic basal ganglia, cerebellar vermis dysplasia, brainstem/corpus callosum hypoplasia, and/or olfactory bulbs agenesis.

A form of pontocerebellar hypoplasia with characteristics of infantile onset of severe global developmental delay with absent speech, hypotonia, feeding problems, dysmorphic craniofacial features, and development of pontocerebellar hypoplasia on brain imaging later in childhood. Other structural abnormalities of the brain, which may already be apparent at an earlier stage, include small hippocampus, thin corpus callosum, periventricular white matter abnormalities, and Dandy-Walker malformation. Seizures, nystagmus, and cortical visual impairment have been reported in some cases.	Finding site	True	Pontine structure	Inferred relationship	Some	2
