3. Karyology Karyotypes of the guinea-pig have been produced by several investigations within recent years (AwA et al., 1;959 OHNeOt al., 161;9 WnTSON et al., 1696 and DOANBORIVJ and GJ,DOMIA,N 167a9, b). The haploid number of chromosomes is 3,2 a relatively large number for a...
About 1:650–1000 children are born with an extra X or Y chromosome, which results in the chromosomal patterns 47,XXY (Klinefelter Syndrome; KS), 47,XXX (Trisomy X or Triple X) or 47,XYY (XYY Syndrome), as compared to the typical 46,XY or 46,XX karyotype in boys and girls. These...
From the original isolate, haploid sporidial strains were generated via micromanipulation of the meiotic products from a single tetrad, yielding the strains Lamole p1A1 and p1A2 that differ in electrophoretic karyotypes only in the mating-specific chromosome. For the work in this report, the ...
The prognosis is variable, depending on the severity of the manifestations and on the quality and timing of treatment.Background/Definition Trisomy X (47,XXX) is a sex chromosome aneuploidy condition in which females have an extra X chromosome, compared to the 46,XX karyotype in typical females...
When a trisomy occurs involving sex chromosomes, there is inherently an additional X or Y chromosome (i.e. 47, XXY‘Klinefelter Syndrome’; 47, XYY ‘Jacob's Syndrome’ or ‘YY Syndrome’; 47, XXX ‘Triple X Syndrome’). Cytogenic (karyotype) analysis offers the earliest and most ...

While macrodiversity (that is, the number of subclones in the whole tumour) reflects the established clonal diversity within a tumour, clonal diversity at a narrow spatial scale, or microdiversity (that is, the number of subclones within a single tumour sample), could represent under-detected ...
Interestingly, XYY karyotypes that do not present with a detectable phenotype have normal behavior and cognitive abilities, and normal serum testosterone levels, suggesting that, although the dosage of X-linked genes is important in normal develop- ment, this may not be the case for Y-linked ...

Diagnosis during the prenatal period by amniocentesis or chorionic villi sampling is common. Indications for postnatal diagnoses most commonly include developmental delays or hypotonia, learning disabilities, emotional or behavioral difficulties, or POF. Differential diagnosis prior to definitive karyotype ...
