REPORT on the First International Workshop on Chromosome 9 held at Girton College Cambridge, UK, 22–24 March, 1992

The meeting was attended by 70 participants whose names and addresses are included in an appendix to this report.Fifty-four abstracts were received and the data presented on posters.The main role of the meeting was seen as the construction of a consensus map of chromosome 9, together with a sharing of knowledge about resources such as hybrids, libraries and new polymorphisms.The group divided into separate working parties to consider 9p, 9cen-9q32, 9q33-9qter, global problems and comparative mapping.The findings of each of these groups are included in this report.There was a separate discussion of resources which is also summarized.Two databases were discussed and demonstrated (GDB by Bonnie Maidak and ldb by Andy Collins).The chromosome 9 workshop was preceded on the afternoon of Sunday, 22 March by a workshop on Tuberous Sclerosis.Because of the relevance of this to chromosome 9q34 a report on this workshop is included in that section.A further subgroup met on 24 March to discuss the CEPH chromosome 9 consortium map and a brief report on their progress was produced.In accordance with the recommendation of the Global group an attempt has been made to reference information in the maps but it is recognized that this is incomplete.
