Login to comment 114 ABCC7 p.Arg1162* Among the most common mutations, R1162X and F508del were found to be more frequent in patients with lower BMD ( p =0.044 and p =0.071, respectively; data not shown). Login to comment 133 ABCC7 p.Arg1162* Their suggestion that some CFTR mutations may be associated with a reduced BMD in CF was partially confirmed by the present study, where R1162X or F508del alleles were found to be more frequent in patients with lower BMD.
