Infants with Canavan usual ly appear normal of the starting time 3-5 months of life, but later those few months, problems with development start to occur. This can included that postp hotshotment of motor skills such as tour over, controlling channelize movement, and sitting without support.

The parents of an one-on-one with an autosomal recessive condition each carry one of the mutated genes, but do not base the symptoms. Basically one of the parents is a carrier or heterozygous for this mutation. The prognosis for Canavan disease is poor.
