Non-progressive congenital ataxia

Non-progressive congenital ataxia (NPCA) is a non-progressive form of cerebellar ataxia which can occur with or without cerebellar hypoplasia.


NPCA is a syndrome and can have diverse causes. It has a genetic basis and inheritance is considered to be autosomal recessive.[1] However, autosomal dominant variety has also been reported.[2] There may be familial balanced translocation t(8;20)(p22;q13) involved.[3]


Neuroimaging like MRI is important. However, there was considerable intrafamilial variability regarding neuroimaging, with some individuals showing normal MRI findings.[4] Early individual prognosis of such autosomal recessive cerebellar ataxias is not possible from early developmental milestones, neurological signs, or neuroimaging.[5]
