4. Bienvenu T, Cazeneuve C, Kaplan JC, Beldjord C (April 3) and Cao A, Rosatelli MC and Leoni GB (May 5) retract their report on 2184insG.
5. Hughes D, Hill A, Graham C (April 20) report the presence of an additional T in intron 18 at position 3601-99.
6. Claustres M (April 22) now reports that the A to C change at 1341+18 in intron 8 is a sequence polymorphism.
7. Estivill E (April 12) corrects the name of their previously reported mutation 1811+1.6kbA->G after more detailed analysis of the region around exon 11 and 12.
8. Malone G and Schwarz M are requesting data for a genotype-phenptype correlation study on E60X. Please see letter and data contribution form (April 4).
9. The CF Genotype-Phenotype Consortium is requesting data for a study on mutations associated with pancreatic sufficiency. Anyone with appropriate data is welcome to contribute. Please see letter and data contribution form from Ada Hamosh.
10. The consortium report on the population variation of common CF mutations has been formally accepted for publication in Human Mutation later this year. Citation should be: The Cystic Fibrosis Analysis Consortium (1994). Population variation of common CF mutations. Human Mutation 4: (in press).
11. I have been working on the idea of establishing an electronic version of the CF mutation database accessible by internet. I will report on the progress of this project. If you use e-mail regularly, please send me a note. My address is <cfdata@sickkids.on.ca>.
