What is the life expectancy of someone with joubert syndrome?

Joubert syndrome is a genetic birth defect in which the area of the brain that controls balance and coordination is underdeveloped. Joubert syndrome occurs in both males and females, in about one in 100,000 births. Joubert syndrome often occurs in a child with no family history of the disorder, but in some children the syndrome appears to be inherited.
