The most common sex chromosomeaneuploidyin humans is theKS, which may manifest with different chromosomal constitution: 47,XXYor mosaic 46, XY/47, XXY, or higher-grade sex chromosomal aneuploidy, that is, 48, XXXY, 49, XXXXY, etc. Although its incidence is high (1:660 in live births an...
Klinefelter's syndrome is a common sex chromosomal abnormality observed in humans, with a prevalence of 1 in 500 males [1–3]. The clinical features are variable but often include infertility, gynecomastia, eunuchoidism, small testes and penis and hypergonadotropic hypogonadism. The syndrome is u...

Sex Chromosome Trisomies (SCTs) are among the most common chromosomal aneuploidies in humans [1], with a prevalence of 1:650–1:1000 of live births [2]. SCT, the presence of an extra X or Y chromosome, leads to the chromosomal patterns of 47,XXX in girls (Triple/Trisomy X), and 47...
Although such anomalies are not common in humans, they do occur and they often have phenotypic consequences. For example, being heterozygous for a deletion of material on the short arm of chromosome 5, which is to say possessing only one copy of that material, results in a disorder known as...
