The infantile form of amaurotic family idiocy.

Description

This infantile form of amaurotic family idiocy is a rare type of gangliosidosis with ubiquitous storage of lipopigments in the lysomas. Onset of symptoms between the ages of 2 and 4 years. Most patients die by the age of 4 to 8 years. After a normal or slightly retarded development, the illness often starts with progressive loss of vision. Progressive spasticity, athetosis, loss of speech, minor convulsions. Later: blindness, frequent respiratory infections, incoordination, tremor, ataxia, spastic weakness, increased tendon reflexes, Babinski signs, mental deterioration, and dysarthria. Both sexes affected. The disturbance is transmitted as an autosomal dominant trait. The condition differs from the other forms of amaurotic idiocy by virtue of lack of fundal changes and the presence of significant cerebellar dysfunction.

First description probably by the Prague psychiatrist Jan Jansky (1877-1921), who in 1910 reported a family with a similar condition.

The infantile form is entered here as Tay-Sachs disease, under Waren Tay, English ophthalmologist and surgeon, 1843-1927; the juvenile form as Stengel's syndrome, under Christian Stengel, German physician in Norway, 1794-1890.
