Whereas SCLC was frequently characterized by multiple allelic losses, suggesting the deletion of the entire chromosomal arm, SCC showed interstitial imbalances.
All tumours were informative with at least one locus; three revealed replication errors (RERs) at multiple microsatellite loci, and interstitial or telomeric allelic deletions were observed in 12 cases.
In a multiple allelic model, PAGE could discriminate different alleles bearing addition or deletion of 1 18 bp as distinct bands that were easily quantifiable by densitometry.
Common CNV polymorphisms (i.e. frequency > 1%) often with multiple allelic states defined by variations in copy number and/or genomic structure; and rare CNVs, that typically lead to deletion or duplication of larger genomic segments and exist in fewer allelic states (i.e., hemizygous or trisomic).
Mutually exclusive large allelic deletions on chromosome 9 within the high FST window between gdv1 and gexp22.
Baker SJ, Preisinger AC, Jessup JM, Paraskeva C, Markowitz S, Willson JK et al. p53 gene mutations occur in combination with 17p allelic deletions as late events in colorectal tumorigenesis.
Here, the identification of two major allelic deletions in the gdv1 3′-intergenic region involved focused inspection of long-read sequence data for a small number of P. falciparum isolates, which then led to analysis of a large numbers of samples, firstly by mapping of short-read sequences to the alternative allelic reference sequences, and secondly by design of primers for PCR-based genotyping.
Allelic deletions were identified by PCR and gel electrophoretic techniques to examine three polymorphisms within the p53 gene in cancer-normal DNA pairs.
We further analysed the metastases with respect to allelic deletions at the chromosomal locus of nm23.
Allelic deletions were founded for 57 patients, of whom 335858%) had CaP.
