A strategy for the characterization of minute chromosome rearrangements using multiple color fluorescence in situ hybridization with chromosome-specific DNA libraries and YAC clones [PDF]

, 1993
The identification of marker chromosomes in clinical and tumor cytogenetics by chromosome banding analysis can create problems. In this study, we present a strategy to define minute chromosomal rearrangements by multicolor fluorescence in situ ...

SupCAM: Chromosome cluster types identification using supervised contrastive learning with category-variant augmentation and self-margin loss

Frontiers in Genetics, 2023
Chromosome segmentation is a crucial analyzing task in karyotyping, a technique used in experiments to discover chromosomal abnormalities. Chromosomes often touch and occlude with each other in images, forming various chromosome clusters. The majority of

Mechanics and dynamics of X-chromosome pairing at X inactivation [PDF]

, 2008
At the onset of X-chromosome inactivation, the vital process whereby female mammalian cells equalize X products with respect to males, the X chromosomes are colocalized along their Xic (X-inactivation center) regions. The mechanism inducing recognition

Comprehensively Characterizing the Cytological Features of Saccharum spontaneum by the Development of a Complete Set of Chromosome-Specific Oligo Probes

Frontiers in Plant Science, 2018
Chromosome-specific identification is a powerful technique in the study of genome structure and evolution. However, there is no reliable cytogenetic marker to unambiguously identify each of the chromosomes in sugarcane (Saccharum spp., Poaceae), which ...

A universal karyotypic system for hexaploid and diploid Avena species brings oat cytogenetics into the genomics era

BMC Plant Biology, 2021
Background The identification of chromosomes among Avena species have been studied by C-banding and in situ hybridization. However, the complicated results from several cytogenetic nomenclatures for identifying oat chromosomes are often contradictory.

Case Report: How whole-genome sequencing-based cell-free DNA prenatal testing can help identify a marker mhromosome

Frontiers in Genetics, 2022
A supernumerary marker chromosome (SMC) is a structurally abnormal chromosome that cannot be characterized by conventional banding cytogenetics. Marker chromosomes are present in 0.075% of prenatal cases.

Identification of candidate genes for dyslexia susceptibility on chromosome 18 [PDF]

, 2010
Background: Six independent studies have identified linkage to chromosome 18 for developmental dyslexia or general reading ability. Until now, no candidate genes have been identified to explain this linkage.
