Abstract

Chromosomal aberrations in 22 Koreans with ovarian carcinomas were investigated by degenerate oligonucleotide primed-polymerase chain reaction comparative genomic hybridization. The common sites of copy number increases were 20q (90%), 17q23∼qter (86%), 8q22∼qter (68%), 3q25∼qter (59%), 6p21 (59%), 11q13 (54%), 16p (40%), 2q31∼qter (36%), 7q (36%), 14q31 (36%), 15q24∼qter (36%), and 1q32∼qter (31%). DNA amplification was identified in 18 carcinomas (82%). The frequent sites of amplification were 20q13.2∼qter, 8q24.1, 17q23∼qter, 3q25∼qter, and 6p21. The most frequent sites of copy number decreases were 4q21∼q31 (54%), 5q13∼q21 (50%), and 13q14∼q21 (45%). The recurrent gains and losses of chromosomal regions identified in this study provide candidate regions that may contain oncogenes or tumor suppressor genes, respectively.
