2. DNA sequence polymorphisms/variations in the coding region
Nucleotide position Amino acid change Exon Reference 2238C/G No change (Leu at 702) 13 Bienvenu T, Cazeneuve C, Kaplan JC, Beldjord C
3. DNA sequence polymorphism elsewhere in the CF gene
Description Location Reference 1716+13G/T G or T at 1716+13 (intron 10) Chillón M, Nunes V, Casals T, Esivill X (Jan 18) 3271+18C/T C or T at 3271+18 (intron 17a) Claustres M (Jan 24) -895T/G T or G at -895 upstream of the cap Bienvenu T, Cazeneuve C, site Kaplan JC, Beldjord C (Feb 11) -329A/G A or G at -329 upstream of the cap Wallace A, Tassabehji M site (Feb 18)
4. Wallace A and Tassabehji M (Jan 21) noted the association of 4279insA with 297-3C->T (reported by Bienvenu et al, NL#55).
5. Casats T, Palacio A, Nunes V and Estivill X raised the possibility that V232D (reported by Costes B et al, Nov 19, NL#60) was a sequence polymorphism (see letter Jan 19).
6. A.J. M. Hill has developed screening test for Q2X and is interested in looking at any patients of Northern Irish descent for the mutation (see letter Jan 28).
7. The consortium report on the population variation of common CF mutations has be provisionally accepted for publication in Human Mutation, with some suggested minor modifications of the text and presentation format. To finish the report, however, I need to seek updates for several mutations. The investigators have been contacted.
