Cystic fibrosis in the population of Reunion Island.

The frequencies of the delta F 508 mutation and haplotypes linked to the cystic fibrosis (CF) gene and detected with DNA probes XV-2C and KM-19 have been studied in the population of Reunion Island, a French province located in the Indian Ocean. The deletion was present in 41.3% of CF chromosomes, whereas this proportion is about 70% in the French population. The delta F 508 mutation was associated with the haplotype B defined by the DNA markers XV-2C (allele 1) and KM-19 (allele 2) in 76.4% of CF chromosomes, while this proportion is over 90% in the French population. Founder effect, genetic drift and admixture can explain these differences.

A splicing mutation in intron 16 of the cystic fibrosis transmembrane conductance regulator gene, associated with severe disease, is common on Reunion Island.

In addition to the frequent delta F508 and Y122X mutations on cystic fibrosis (CF) chromosomes of patients from Reunion Island, one splicing mutation, 3120+1G-->A is observed relatively frequently (12.5%) in this group, in comparison with the French metropolitan population (<0.001 %). This mutation, disrupting the 5' splice donor site of intron 16, can be detected easily by restriction enzyme BstNI digestion. In 2 CF patients homozygous for this mutation, the clinical pattern was severe, with both pancreatic insufficiency and respiratory symptoms.
