Infants with Canavan u sually appear normal of the low gear 3-5 months of life, but later those few months, problems with development start to occur.

Feeding and swallowing difficulties, seizures, and sleep disturbances may also develop. (Genetic Home Reference, 2008). good deal inherit Canavan disease from an autoso mal recessive pattern, which means that bot! h copies of the gene in apiece cell have mutations. The parents of an man-to-man 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. Usually the death occurs before the age 4 and both(prenominal) survive in their late teens and archaeozoic twenties.
