Chromosomal rearrangements in cancer
Many cancers exhibit chromosomal rearrangements. These rearrangements can be simple with a single balanced fusion preserving the proper complement of genetic information or they can be complex with one or more fusions that distort this balance. A range of technological advances has improved our ability to detect and understand these rearrangements leading to speculation of causal mechanisms inc...
متن کاملRearrangements and chromosomal evolution.
Comparisons of the genome sequences of related species suggests varying patterns of chromosomal rearrangements in different evolutionary lineages. In this review, I focus on the quantitative characterization of rearrangement processes and discuss specific inventories that have been compiled to date. Of particular interest are the statistical distribution of the lengths of inverted or locally tr...
متن کاملChromosomal rearrangements and speciation.
Several authors have proposed that speciation frequently occurs when a population becomes fixed for one or more chromosomal rearrangements that reduce fitness when they are heterozygous. This hypothesis has little theoretical support because mutations that cause a large reduction in fitness can be fixed through drift only in small, inbred populations. Moreover, the effects of chromosomal rearra...
متن کاملComplex nature of apparently balanced chromosomal rearrangements in patients with autism spectrum disorder
BACKGROUND Apparently balanced chromosomal rearrangements can be associated with an abnormal phenotype, including intellectual disability and autism spectrum disorder (ASD). Genome-wide microarrays reveal cryptic genomic imbalances, related or not to the breakpoints, in 25% to 50% of patients with an abnormal phenotype carrying a microscopically balanced chromosomal rearrangement. Here we perfo...
متن کاملExceptional Complex Chromosomal Rearrangements in Three Generations
We report an exceptional complex chromosomal rearrangement (CCR) found in three individuals in a family that involves 4 chromosomes with 5 breakpoints. The CCR was ascertained in a phenotypically abnormal newborn with additional chromosomal material on the short arm of chromosome 4. Maternal karyotyping indicated that the mother carried an apparently balanced CCR involving chromosomes 4, 6, 11,...
