dc.description.abstract | DNA from 130 individuals was studied with up to 18 (primarily cDNA) probes for the frequency of variants in this initial experiment to determine the feasibility of this approach to screening for germinal gene mutations. This approach, a modification of the usual restriction enzyme mapping strategy, focuses on the detection of insertion/deletion/rearrangement (I/D/R) variants, because the DNA is digested with only two restriction enzymes before transfer to membranes and hybridization with an extensive series of unrelated probes. Some 4000 noncontiguous, independent DNA fragments ("loci"), functional loci, pseudogenes or anonymous fragments, (a total of ~ 77 400 kb) were screened. 19 different classes and 31 copies of presumably I/D/R variants were detected while 4 different classes and 24 individuals exhibiting base substitution variants were observed. 18 of the 19 I/D/R classes were rare variants, that is, each were observed at a frequency, within this population, of less than 0.01; 3 of the base substitution classes existed at polymorphic frequencies and only 1 was a rare variant. 10 of the I/D/R classes, occurring in a total of 18 individuals, were detected with probes which are not known to be associated with repetitive elements. This is a variant frequency for I/D/R variants without known repetitive elements of 0.15 classes and 0.23 copies for each 1000 kb screened; this would extrapolate to 1600 such variant sites in the genome of each individual. Within the context of a mutation screening program, the rare variants, either with or without repetitive elements, would have a higher probability of being de novo mutations than would polymorphic variants; this former group would be the focus of family studies to test for the heritability of the allele (fragment pattern). Sufficient DNA probes are available to screen a significant portion of the human genome for genetic variation and de novo mutations of this type. | en_US |
