No. Sentence Comment

3 Results: CFTR activity in sweat gland, upper airways and distal intestine was normal for homozygous carriers of G314E or L997F and in the range of F508del homozygotes for homozygous carriers of E92K, W1098L, R553X, R1162X, CFTRdele2(ins186) or CFTRdele2,3(21 kb). Login to comment
56 The homozygotes for E92K,16 W1098L or M1101K17 showed highly elevated sweat chloride concentrations in the CF range on several occasions, whereas the homozygotes for G314E18 or L997F19 20 had normal sweat electrolytes like non-CF healthy controls (table 2). Login to comment
61 The transport rates were in the upper CF range (E92K, W1098L, one M1101K sibling), in the intermediate range between CF and non-CF (the other two M1101K siblings) or in the normal range (L997F, G314E) (fig 1C). Login to comment
