NEWSLETTER #25, August 30, 1990


1. A list of new mutations and variations:

a. Goossens M, Fanan P, Ghanem N, and Vidaud M report 2 mutations in exon 9 (3732delA and K1200E), 2 sequence variations in exon 12 (1816G->A for V562I, 1859G->C for G576A) and 1 variation in exon 19 (3617G->T for R1162L). Since the two exon 9 mutations were found on the same CF chromosome, they represent just one allele (see letter).

b. Nunes V and Estivill X report a sequence variation (873C->T) in exon 6a; they also note an error in their previous report where the intron sequence variation should read 290+12C->T (not 372+12C->T) (see letter).

c. Highsmith WE, Strong T, Burch N, Silverman LM, Collins FS, Boucher RC and Knowles MR report a (probable) splicing mutation for exon 14b (2751+5G->A). Please refer to their letter for details.

d. Bozon D, Zielenski J, Rininsland F, Rommens J and Tsui L-C: L1077P, a T to C change at nucleotide position 3362. The change was found in Toronto family #55. The mutation is on the maternal chromosome with haplotype IIIc. It can be detected by ASO hybridization, with the N sequence: TGA AAC TCT GTT CCA C and the CF sequence:TGA AAC TCC GTT CCA C. Genomic DNA may be amplified with 17bi-5 and 17bi-3. Temp for hybridization 37[[ring]]; final washing temp is 42[[ring]] in 2x SSC. We did not find this mutation in 27 other CF chromosomes (9 from group III) nor in 27 N chromosome (16 from group III).

2. There were a number of errors in a previous printout of the CFTR genomic DNA sequence (Newsletter #22).

a. Exon 3- a space should be inserted in the third line, between codon TTC and TAT;

b. Exon 10- there should be no space between TTTTA and TTTCC in the second line and the following sequence:


should be inserted between TTATGCATA and TGGCTCCAT in the fifth line; the PCR product should be 491 bp;

c. Exon 13- a space should be inserted between codon TTT and GTC;

d. in the list of PCR primers, 10D should read ACACGCCCTCCTCTTTCGTG;

6Ai-3 should read CTATGCATAGAGCAGTCCTG; an extra 4 bases (TCAA) was inserted in X13B-5 which should read TCAATCCAATCAACTCTATACGAA;

e. there are some errors in the sizes of the predicted PCR products; they should be 561 bp for exon 9, 449 for 14b, 579 for 17a, 463 for 17b, and 477 for 21;

f. there are several disagreement between the regions underlined and the PCR oligonucleotides shown in the table; please use the ones shown in the table.

We thank E. Edkins for noting some of the errors.

3. There are 2 pieces of technical information, from Chehab et al on the GATT repeat in front of exon 6b (originally reported by Horn et al) and, Schwarz and Super on R560T (Kerem et al. PNAS accepted) (see letters). Schwarz and Super also request clinical information for [[Delta]]I507.

4. For those members who have trouble receiving the previous Newsletters by FAX, you will receive them (issues #14-#25) in the mail by the middle of September. If you notice any mistakes in those issues, please drop me a note. If you want a copy of the compiled issues #1-#13, please also let me know.

5. Repeat announcement: A general meeting of the Consortium will be held at the next International CF Congress which will be held between October 3 and 6, 1990, in Arlington, Virginia, USA. The time of the meeting is tentatively scheduled for the evening of October 4; the exact time and location will be announced on a later date. The registration deadline for the Congress is September 5. Please call the US CF Foundation if you have any questions regarding registration to the Congress: (301) 951-4422; FAX number. (301) 951-6378.

Best regards,
