Age range for pediatric onset disease is younger than 16 years by definition. No specific age of onset is excluded. The median age at onset is 12 years, based on reported pediatric series. The youngest reported age at onset is 2 years. A recent 15-year retrospective study concluded the mean age at disease onset was 10.7 years. [9]
