I appreciate the letter by Dr Ruiz-Linares and am happy to learn that the C212Y substitution has been found in a patient in Colombia. We considered our contribution to be original because we presented that finding as a poster at the Sixth International Congress of Parkinson's Disease and Movement Disorders in Barcelona, Spain, in June 2000,1 and at that time we were not aware of the publication by Dr Ruiz-Linares.2
