What occurs to people with gaucher disease type 2 that don't get treated?

Not good: "gaucher disease has the earliest onset, within the first 3 to 6 months of life and it is fatal; causing death before 2 years of age. Due to the shortened lifespan, babies with type 2 will not survive long enough to develop some symptoms experienced by individuals with type 1 and type 3." not sure treatment will help...This is very sad. http://www.gaucherdisease.org/gaucher-disease-type2-type3.php.
