CF databases: c.1720C>T , p.Pro574Ser (CFTR1) D , The P574S mutation was simultaneously detected in two families with no apparent relation but living in the center part of France (Auvergne). The P574S mutation was detected in CFTR gene by DGGE and identified by sequencing. In one family this mutation was associated with N1303K, in the other family it was associated with the F508del.
c.1721C>A , p.Pro574His (CFTR1) ? , Although the amino acid pro at this position is not highly conserved across different ATP-binding folds, his seems to be a drastic substitution. This change is not detected in 52 other CF chromosomes nor 15 normal chromosomes, 4 of which have the same group IV haplotype.
