Age-associated mosaicism and polyploidy in Down's syndrome
(Elsevier B.V., 1998-01-12)
Age-related increases in the frequencies of cells with chromosome 21 loss and of polyploid cells were documented in short-term peripheral blood lymphocyte cultures from 54 patients with Down's syndrome (DS), ages 0 to 48 ...
Reproductive strategies and chromosomal aberrations affect survival in the Rivuliid fish Hypsolebias sertanejo
(Cambridge Univ Press, 2021-02-01)
Rivulidae comprises a family of fish largely distributed in Brazil that includes 201 species, of which 125 are considered endangered. This fact emphasizes the need for development of conservation strategies including studies ...
Insight into the mechanisms and consequences of recurrent telomere capture associated with a sub-telomeric deletion
(Springer, 2018-09-01)
A complex mosaicism of the short arm of chromosome 1 detected by SNP microarray analysis is described in a patient presenting a 4-Mb 1p36 terminal deletion and associated phenotypic features. The array pattern of chromosome ...
Chromosomal Variability in Akodon sp. (Rodentia, Cricetidae)
(1982-01-01)
In a sample of 30 specimens of Akodon sp. (Rodentia, Cricetidae), diploid numbers of 2n=24 and 2n=25 along with two mosaic cases with 2n=25/26 and 2n=23/24 were found. The inter and intraindividual chromosome variability ...
Sex chromosomal abnormalities associated with equine infertility: validation of a simple molecular screening tool in the Purebred Spanish Horse
(Wiley Blackwell Publishing, Inc, 2017-08)
Chromosomal abnormalities in the sex chromosome pair (ECAX and ECAY) are widely associated with reproductive problems in horses. However, a large proportion of these abnormalities remains undiagnosed due to the lack of an ...
Estudo citogenético em equinos para detecção de portadores de monossomia do cromossomo X
(Arquivo Brasileiro Medicina Veterinaria Zootecnia, 1996-08-01)
A cytogenetic study of 22 mares with fertility has showed that four of them had 63,X/64,XX mosaicism. The X-chromosome has presented the expected interstitial heterochromatic C - banding located in the long arm, besides ...
