|Experimental: Cholesterol supplementation||
Drug: crystalline cholesterol oil-based suspension
200 mg/mL suspension of crystalline cholesterol in oil. Dosage (generally 75-300 mg/kg/day in divided doses) is based on initial cholesterol levels and regulated to increase, yet maintain, cholesterol levels no higher than normal ranges.
- Number of Responders [ Time Frame: Every 3-6 months for an approximate median of 5 years ]Responders was defined as an increase in total serum cholesterol and a decrease in 7-DHC (7-Dehydrocholesterol), and 8-DHC (8-Dehydrocholesterol) were measured on all participants.
- Number of Growth Responders [ Time Frame: Every 3-6 months for an approximate median of 5 years ]Growth response was defined as an increase in general health, growth, and behavior.
- Number of Participants With Improved Neuropsychological Development [ Time Frame: Every 3-6 months for an approximate median of 5 years ]Improved neuropsychological development is defined as progressively achieving developmental milestones
