Technical limitations associated with current mutation screening protocols have placed increased emphasis on the development of new technologies to simplify these procedures. High-density arrays of &gt;90,000oligonucleotide probes, 25 nucleotides in length, were designed to screen for all possible heterozygous germ-line mutations in the 9.17-kb coding region of the <jats:italic>ATM<\/jats:italic> gene. A strategy for rapidly developing multiexon PCR amplification protocols in DNA chip-based hybridization analysis was devised and implemented in preparing target for the 62 <jats:italic>ATM<\/jats:italic>coding exons. Improved algorithms for interpreting data from two-color experiments, where reference and test samples are cohybridized to the arrays, were developed. In a blinded study, 17 of 18 distinct heterozygous and 8 of 8 distinct homozygous sequence variants in the assayed region were detected accurately along with five false-positive calls while scanning &gt;200 kb in 22 genomic DNA samples. Of eight heterozygous sequence changes found in more than one sample, six were detected in all cases. Five previously unreported sequence changes, not found by other mutational scanning methodologies on these same samples, were detected that led to either amino acid changes or premature truncation of the ATM protein. DNA chip-based assays should play a valuable role in high throughput sequence analysis of complex genes.<\/jats:p>","DOI":"10.1101\/gr.8.12.1245","type":"journal-article","created":{"date-parts":[[2017,5,3]],"date-time":"2017-05-03T00:28:49Z","timestamp":1493771329000},"page":"1245-1258","source":"Crossref","is-referenced-by-count":82,"title":["Strategies for Mutational Analysis of the Large Multiexon <i>ATM<\/i> Gene Using High-Density Oligonucleotide Arrays"],"prefix":"10.1101","volume":"8","author":[{"given":"Joseph G.","family":"Hacia","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bryan","family":"Sun","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nathaniel","family":"Hunt","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Keith","family":"Edgemon","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Deborah","family":"Mosbrook","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christiane","family":"Robbins","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephen P.A.","family":"Fodor","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Danilo A.","family":"Tagle","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Francis S.","family":"Collins","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"246","published-online":{"date-parts":[[1998,12,1]]},"reference":[{"key":"2021111810283921000_8.12.1245.1","doi-asserted-by":"publisher","DOI":"10.1016\/S0165-4608(96)00328-7"},{"key":"2021111810283921000_8.12.1245.2","doi-asserted-by":"publisher","DOI":"10.1038\/ng0797-226"},{"key":"2021111810283921000_8.12.1245.3","doi-asserted-by":"crossref","unstructured":"Branham R.L.
