Skin Biopsy
A very small skin sample will be taken from the participant's arm. This will only be performed while the patient is under sedation for clinical purposes (e.g. exam under anesthesia, MRI, or other procedure requiring sedation).
Blood Draw
About 1 teaspoon of blood will be drawn from the participant's arm or from a central line catheter if present. Blood collection will be done at the same time the participant has blood drawn for routine clinical care.
