PDGFRA gene rearrangements are frequent genetic events in PDGFRA-amplified glioblastomas.
Gene rearrangement in the form of an intragenic deletion is the primary mechanism of oncogenic mutation of the epidermal growth factor receptor (EGFR) gene in gliomas. However, the incidence of platelet-derived growth factor receptor-α (PDGFRA) gene rearrangement in these tumors is unknown. We investigated the PDGFRA locus in PDGFRA-amplified gliomas and identified two rearrangements, including...
متن کاملO-7: Y Chromosome Microdeletions Are Not Associated with Spontaneous Recurrent Pregnancy Loss in A Sinhalese Population in Sri Lanka
Background: Many advances have been made in reproductive medicine yet the spontaneous loss of a pregnancy remains the most common complication of pregnancy. The aetiology of spontaneous recurrent pregnancy loss (RPL) is multifactorial. Y chromosome microdeletions are found in approximately 7% of men with low sperm counts and, compared to the general population, a higher frequency of spontaneous...
متن کاملChromosome rearrangements in Dictyostelium discoideum.
A tandem duplication (D350(III,III] of the whiB to radB interval of linkage group III has been characterized. The gene order on the duplication-bearing chromosome is: centromere, whiB500, radB+, whiB+, radB24, bsgA5, acrC4. Slow-growing, duplication-bearing strains (yellow-spored, radiation-resistant) produced four classes of faster growing sectors involving the whiB and radB loci: white-spored...
متن کاملHow to recognize and diagnose chromosome rearrangements
In most eukaryotes, chromosome rearrangements are recognized cytologically by visibly altered chromosome structure, or genetically by altered linkage relations. The first translocations in Neurospora were detected and verified using these methods (McClintock 1945, Houlahan et al. 1949). However, characteristics of Neurospora provide an easier method that depends on ascospore pigmentation, and t...
متن کاملChromosome rearrangements in Caenorhabditis elegans.
A method for selecting unlinked duplications of a part of the X chromosome of C. elegans is described. Five such duplications have been identified. One of them, Dp (X;V)1, is translocated to linkage group V, where it suppresses crossing over along the left half of linkage group V. Dp(X;V)1 homozygotes grow slowly and are sterile. The other four duplications are associated with chromosome fragme...
