Primary Objective: To examine the range of tissue frataxin (FXN) concentrations in the buccal cells, blood, and skin cells of normal healthy volunteers without FRDA.~Secondary Objective: To examine the range of specific ribonucleic acids (RNAs), other proteins, and specialized lipids in the buccal cells, blood, and skin cells of normal healthy volunteers without FRDA.
To examine range of tissue frataxin (FXN) concentrations, specific ribonucleic acids, other proteins and specialized lipids in the buccal cells, blood, and skin cells of normal healthy volunteers without Friedreich's ataxia (FRDA).
