92 Since L1227S was associated with the 3272-26A→G mild mutation, it is difficult to judge the possibility of CF mutations in close relatives, for whom the Kanavakis, E., Tzetis, M., Antoniadi, T. et al. (1998) Cystic fibrosis mutationrisk of having a child presenting a pathological CFTR-mediated screening in CBAVD patients and men with obstructive azoospermia or phenotype is higher than for the general population.
