[David Ray]

Is anyone out there aware of anyone with a neurological condition which
has been diagnosed as an infintile form of spinal musclular atrophy which
has been the case of somone who is in a wheel chair, was 17 years old, now is 38 
years old and has two completely normal children?  She is completely normal in all
respects except for the fact that she is not strong enought to walk/?
