第七届国际人类基因定位会议(HGM 7)已于1983年8月21日至26日在美国Los Angeles举行。由于适逢首届会议(New Haven,1973)的十周年,本届会议盛况空前,与会者近200人。本届会议报告在人基因组已定位的基因数目已达824个,与六届会议(Oslo,1981)所报告的437个基因位点比较增加了近一倍(表1)。差不多每隔一天,便有一个新的基因定位。据这样的增长速度估计,至下届会议前的两年中,至少可定位1500个墓因.至本世纪末,可能定位的基因将达10,500个;2021年将达86,500个.据目前最大的估计,人的基因组约含十万个基因.这充分说明人类基因定位的最终完成,已不再是可望而不可即的事了。本届会议的最显著特点是分子生物学技术在基 The Seventh International Conference on Human Genetics (HGM 7) was held in Los Angeles, the United States, from August 21 to August 26, 1983. Due to the tenth anniversary of the inaugural meeting (New Haven, 1973), this session was unprecedented in popularity with nearly 200 participants. This meeting reported that the number of genes that have been mapped in the human genome has reached 824, nearly doubling the 437 reported in six sessions (Oslo, 1981) (Table 1). Almost every other day, there is a new gene locus. According to this rate of growth, at least 1500 abortions may be targeted for the two years leading up to the next session, with as many as 10,500 genes likely to be targeted by the end of the century and 86,500 by 2021. According to the most recent estimates , Human genome contains about 100,000 genes.This fully shows that the final completion of human gene positioning is no longer an exaggeration. The most prominent feature of this session is molecular biology technology in the base
