Simultaneous detection of the two prevalent mutations in the cystic fibrosis gene in Reunion Island

A rapid method for the diagnosis of the most frequent cystic fibrosis mutations in the Reunion Island is described based on a coamplification polymerase chain reaction (PCR) followed by a single digestion using MseI . We have used this strategy to detect the two most frequent mutations in this area: ΔF508 (in exon 10) and Y122X (in exon 4). These two mutations account for 70% of the CF chromosomes. This diagnosis method, which is rapid, easy, direct, and inexpensive, allows adult and neonatal carrier screening in this population. © 1993 Wiley‐Liss, Inc.
