Cerebellar ataxia and mental retardation in a child with an inherited satellited chromosome 4q.
We identified a case of familial satellited chromosome 4q through a child with cerebellar ataxia and mental retardation. No loss of genetic material could be demonstrated at the molecular level but other possible mechanisms of this association are discussed. We conclude that in these cases genetic counselling should be reassuring.
