人类基因组计划已经产生了估计80,000到100,000个基因的核苷酸序列,其中只有一小部分具有已知的作用。单靠核苷酸序列信息不足以预测基因功能。揭示基因功能的最有力的方法之一,如在细菌、蠕虫、酵母和苍蝇中所展示的,是产生突变并在表型和分子水平上表征它们。鉴于小鼠和人类之间的生理和解剖学相似性,在小鼠中建立的基因型-表型关系可以外推到人类综合征。描述了一种新的方法在小鼠中使用loxP/Cre工程产生毛色标记的大缺失的功能遗传分析。然后可以通过在表型驱动的筛选中用N-乙基-N-亚硝基脲诱变来切割单倍体区域,以获得关于小鼠基因组的任何期望区域中的基因的功能信息。
The Human Genome Project has generated nucleotide sequences from an estimated 80,000 to 100,000 genes, only a small fraction of which have a known role. Nucleotide sequence information alone is insufficient to predict gene function. One of the most powerful ways of revealing gene function, as demonstrated in bacteria, worms, yeast, and flies, is to generate mutations and characterize them at both the phenotypic and the molecular levels. Given the physiological and anatomical parallels between mouse and human, genotype-phenotype relationships established in mice can be extrapolated to human syndromes. A new method is described for functional genetic analyses in the mouse that uses loxP/Cre engineering to generate coat color-tagged large deletions. The haploid regions can then be dissected by mutagenesis with N-ethyl-N-nitrosourea in phenotype-driven screens to obtain functional information on genes in any desired region of the mouse genome.
