The PCR localization method of somatocyte hybrid cell is that DNA is navigated to concrete chromosomal quick method.Use Oligonucleolide primers of the present invention,, can utilize one group to realize inferior location from specific chromosomal fragment or a large amount of genomic clone by similar approach.Other the similar strategy that can be used for chromosomal localization comprises in situ hybridization, uses the karyomit(e) prescreen and the hybridization preliminary election of the airflow classification of mark, thereby makes up the special cDNA storehouse of karyomit(e).

The cDNA clone is carried out fluorescence in situ hybridization (FISH) with Metaphase Chromosome, can in a step, accurately carry out chromosomal localization.The summary of this technology is referring to Verma etc., Human Chromosomes:a Manualof Basic Techniques, Pergamon Press, New York (1988).

In case sequence is positioned to chromosome position accurately, the physical location of this sequence on karyomit(e) just can be associated with the gene map data.These data for example are found in, V.Mckusick, MendelianInheritance in Man (can by with the online acquisition of Johns Hopkins University Welch Medical Library).Can pass through linkage analysis then, determine gene and navigated to relation between the disease on the chromosomal region already.

Then, need to measure ill and not cDNA between diseased individuals or genome sequence difference.If observe certain sudden change in some or all of diseased individuals, and this sudden change is not observed in any normal individual, then this sudden change may be the cause of disease of disease.More ill and diseased individuals not is usually directed at first seek the variation of structure in the karyomit(e), as from the horizontal visible of karyomit(e) or use based on detectable disappearance of the PCR of cDNA sequence or transposition.Resolving power according to present physical mapping and assignment of genes gene mapping technology, being accurately positioned to the cDNA of the chromosomal region relevant with disease, can be a kind of (the supposing that 1 megabasse mapping resolving power and every 20kb are corresponding to a gene) between 50 to 500 potential Disease-causing genes.
