Summaries for Cerebellar Hypoplasia

NIH Rare Diseases : 49 Cerebellar hypoplasia is a neurological condition in which the cerebellum is not completely developed or is smaller than it should be. It may occur with a variety of congenitalsyndromes, metabolic disorders and neurodegenerative disorders; therefore signs and symptoms may depend upon the associated condition an affected individual has. The most common findings are developmental and speech delay, poor muscle tone (hypotonia), ataxia and abnormal ocular (eye) movements. Cerebellar hypoplasia may range from mild or partial underdevelopment to complete absence (agenesis). It may affect only the cerebellum, or also affect other central nervous system structures. The inheritance pattern may differ depending on the underlying cause of the condition. Treatment is generally symptomatic and supportive and depends upon the underlying disorder and the severity of symptoms. Last updated: 10/26/2015

MalaCards based summary : Cerebellar Hypoplasia, also known as cerebellar hypoplasia-tapetoretinal degeneration syndrome, is related to lissencephaly with cerebellar hypoplasia and lissencephaly, and has symptoms including ataxia, nystagmus and muscular hypotonia. An important gene associated with Cerebellar Hypoplasia is OPHN1 (Oligophrenin 1), and among its related pathways/superpathways are Neuroscience and Reelin signaling pathway. Affiliated tissues include cerebellum, eye and brain, and related phenotypes are Increased shRNA abundance (Z-score > 2) and Increased shRNA abundance (Z-score > 2)

NINDS : 50 Cerebellar hypoplasia is a neurological condition in which the cerebellum is smaller than usual or not completely developed.  Cerebellar hypoplasia is a feature of a number of congenital (present at birth) malformation syndromes, such as Walker-Warburg syndrome (a form of muscular dystrophy. It is also associated with several inherited metabolic disorders, such as Williams syndrome, and some of the neurodegenerative disorders that begin in early childhood, such as ataxia telangiectasia.   In an infant or young child, symptoms of a disorder that features cerebellar hypoplasia might include floppy muscle tone, developmental or speech delay, problems with walking and balance, seizures, intellectual disability, and involuntary side to side movements of the eyes.  In an older child, symptoms might include headache, dizzy spells, clumsiness, and hearing impairment.
