Interesting...........No cause of death revealed, but foul play and drug use have been ruled out.
Bob Saget's sister was diagnosed with Scleroderma an immune system defect.
I have no idea if it runs in families but... Scleroderma shortens life expectancy by
8 years with pulmonary hypertension as most common cause of death and a higher risk for some cancers ie liver and bladder.
