abstract：:The genomic aberration profile of chromosome 20q in distal CIN colon carcinomas was analysed using allelotyping and CGH arrays. Allelotyping revealed carcinomas with allelic imbalance along the full long arm, and carcinomas with fully non-aberrant 20q. Oligonucleotide-based CGH showed that among the carcinomas without...
