AUTOSOMAL RECESSIVE CONGENITAL CEREBELLAR ATAXIA DUE TO MGLUR1 DEFICIENCY
Alternate names
AUTOSOMAL RECESSIVE CONGENITAL CEREBELLAR ATAXIA DUE TO MGLUR1 DEFICIENCY Is also known as autosomal recessive spinocerebellar ataxia type 13, scar13, autosomal recessive congenital cerebellar ataxia due to metabotropic glutamate receptor 1 deficiency
Description
Autosomal recessive congenital cerebellar ataxia due to MGLUR1 deficiency is a rare, genetic, slowly progressive neurodegenerative disease resulting from MGLUR1 deficiency characterized by global developmental delay (beginning in infancy), mild to severe intellectual deficit with poor or absent speech, moderate to severe stance and gait ataxia, pyramidal signs (e.g. hyperreflexia) and mild dysdiadochokinesia, dysmetria, tremors, and/or dysarthria. Oculomotor signs, such as nystagmus, strabismus, ptosis and hypometric saccades, may also be associated. Brain imaging reveals progressive, generalized, moderate to severe cerebellar atrophy, inferior vermian hypoplasia, and/or constitutionally small brain.
Most common symptoms of AUTOSOMAL RECESSIVE CONGENITAL CEREBELLAR ATAXIA DUE TO MGLUR1 DEFICIENCY
- Intellectual disability
- Seizures
- Global developmental delay
- Short stature
- Generalized hypotonia
