Karyotype heterogeneity and unclassified chromosomal abnormalities.
In a departure from traditional gene-centric thinking with regard to cytogenetics and cytogenomics, the recently introduced genome theory calls upon a re-focusing of our attention on karyotype analyses of disease conditions. Karyotype heterogeneity has been demonstrated to be directly involved in the somatic cell evolution process which is the basis of many common and complex diseases such as c...
متن کاملGenome Size, Karyotype Polymorphism and Chromosomal Evolution in Trypanosoma cruzi
BACKGROUND The Trypanosoma cruzi genome was sequenced from a hybrid strain (CL Brener). However, high allelic variation and the repetitive nature of the genome have prevented the complete linear sequence of chromosomes being determined. Determining the full complement of chromosomes and establishing syntenic groups will be important in defining the structure of T. cruzi chromosomes. A large amo...
متن کاملChromosomal characteristics and karyotype evolution of Oxyopidae spiders (Araneae, Entelegynae).
We made a cytogenetic analysis of four species of Oxyopidae and compared it with the karyotype data of all species of this family. In Hamataliwa sp, the mitotic cells showed 2n♂ = 26+X(1)X(2) and telocentric chromosomes. The 2n♂ = 28, which has been described for only one oxyopid spider, is the highest diploid number reported for this family. Peucetia species exhibited distinct karyotype charac...
متن کاملChromosomal disorders and male infertility.
Infertility in humans is surprisingly common occurring in approximately 15% of the population wishing to start a family. Despite this, the molecular and genetic factors underlying the cause of infertility remain largely undiscovered. Nevertheless, more and more genetic factors associated with infertility are being identified. This review will focus on our current understanding of the chromosoma...
متن کاملChromosomal disorders: background and neuroradiology.
Chromosomal aberrations, and their associated syndromes of dysmorphism and malformations of multiple organ systems, have been long recognized as significant causes of severe mental impairment. With a few major exceptions, these clinical syndromes have only recently been catalogued as systematically ( 1, 2) as have been single-gene disorders. The neuropathologic features of many of these syndrom...
