There are few reports about the incidence of the Delta F508 mutation in Lat
in American countries, We show the study of the Delta F508 mutation and the
seven most common "European" mutations in 10 Ecuadorian CF affecteds, The
incidence of Delta F508 mutation found was 25% and none of the other seven
was detected in our population, which indicates that at least 60% of the mu
tations in the studied population are different from most common in Europe,
Similar data have been reported in other Amerindian populations, therefore
it is suggested that Cystic Fibrosis in Ecuador-and other Amerindian count
ries in Latin America-have a different ethiology than that of Caucasian pop
ulations. Hum Mutat 14:348-350, 1999. (C) 1999 Wiley-Liss, Inc.
