Incidence of cystic fibrosis in ethnic Italians and Greeks and in Australians of predominantly British origin.

The incidence of cystic fibrosis among the Australian born children of parents born in Italy was 1:3 625 live births and among Australian born children of parents born in Greece 1:3 726. These incidences were significantly lower than the incidence for cystic fibrosis of 1:2 021 in children born to Australian born parents, about 90% of whom have ancestors born in the British Isles. The figures suggest there are significant variations in the incidence of cystic fibrosis in different European populations.
