NEWSLETTER #27, OCTOBER 2, 1990

_____________________________________________________________

1. Dörk, Wulbrand and Tümmler report a possible splice mutation at the 5' end of exon 20 (3850-3T->G) (see letter attached).

2. Goossens, Fanen, Vidaud, Ferrari and Cremonesi report a frameshift mutation in exon 11 (1784delG) (see letter).

3. Goossens, Fanen, Vidaud, Romeo, Ronchetto, Telleria and Devoto report a nonsense mutation in exon 11 (Q552X) (see letter).

4. A compile copy of the back issues of Newsletter #14-#26) will be distributed through regular mail before the end of this week. If you do not receive it within reasonable time, please drop me a note. A copy of the compiled Newsletter #1-13 will also be sent to those members who join after Paril 5, 1990.

5. A summary table of the population screening result is attached. There is significant variation among different centers. Since the entire table is 20 pages long it would be too expensive to send it by FAX; it will be included in the back issues.

Best regards,

Lap-Chee Tsui
