128 Further alignment showed that the R765Q mutation in ABCC6/MRP6 is the positional equivalent of both the R560T mutation in ABCC7,28 and the R842G mutation in ABCC8.29 Similarly, additional possible positional equivalent clusters of conserved and mutated residues were found between ABCC6/ MRP6 and ABCC2 (R1114H and R1150H),30 ABCC6/MRP6 and ABCC7 (3775 del T and W1204X),31 ABCC6/MRP6 and ABCR (R1459C and H2128R, 4220InsAGAA and R2077W, R1141X and L1631P).32,33 Interestingly, for both ABCC7 and ABCR, models were postulated in which the severity of the disease shows an inverse correlation with the predicted transport activity of the ABC protein.

76 Other than ⌬F508 itself and I1027T, typically occurring in cis-, only two individual mutations, W1204X and L206W, were observed with ⌬F508 more than once (twice each) in this study. Login to comment
82 In contrast, among the 78 non-ACMG/ACOG mutations observed in our study group, 24 were noted two or more times, including six instances of the splice site mutation 406-1GϾA, and four instances of W1204X. Login to comment
83 While ⌬F508 was homozygous in six subjects, seven other less common alleles (G542X, W1204X, R75X, V232D, E116K, T501A, 3272-26 AϾG) were also seen in the homozygous state. Login to comment

204 Some of the disparity in mutation detection between Caucasians and Hispanics could be alleviated by adding at least seven additional mutations to the currently recommended ACOG/ACMG panel of 25 mutations: 406-1GϾA, W1204X, R75X, 2055del9ϾA, 3876delA, S549N, and 935delA (Table 4).

221 For carrier screening of Hispanic patients, inclusion of additional mutations with significant frequency in the Hispanic CF population (especially 406-1GϾA, W1204X, R75X, 2055del9ϾA, 3876delA, S549N, and 935delA) may be helpful to supplement the ACMG/ACOG panel. Login to comment
