OA) Human aneuploidy usually conveys an adaptive advantage in humans. B) A monosomy is more frequent than a trisomy. Monosomy X is the only viable monosomy known to occur in humans. For example, it is well known that aneuploidies are the most common chromosomal abnormalities, including trisomy 21 (Down’s syndrome), trisomy 18 (Edwards’ syndrome), trisomy13 (Patau’s syndrome), and sex chromosome aneuploidies (SCA). 2 SCAs are caused by the presence of an abnormal number of sex chromosomes (X or Y) in a cell, and they include 45,X (Turner syndrome), 47,XXX (Triple X Request PDF | Gene Copy Number Quantification of SHOX , VAMP7 , and SRY for the Detection of Sex Chromosome Aneuploidies in Neonates | Aims: To explore the feasibility of detecting sex chromosome If we focus only on the range of female age <35 years, namely, the least populated class according to woman age in this study, the prevalence of 47,XXY karyotype among male blastocysts without autosomal aneuploidies was 0.2%, which is in line with the prevalence reported in male newborns from previous epidemiological studies (0.1–0.2%).

Aneuploidies in newborns

Aneuploidy refers to a disruption in an organism's normal number of chromosomes. Many serious birth defects and congenital conditions are linked to aneuploidy, as the chromosomes are the repository of DNA, a crucial component of life.

an aneuploidy resulting in the deletion of a chromosome segment is less serious than a duplication. b.

Phenotypic characteristics associated with a number of specific aneuploidies in the mouse are discussed. Emphasis is placed on the effects of trisomy 16. Genetic homology between mouse chromosome 16 and human chromosome 21 has led investigators to suggest that analogous mechanisms will be responsible for the developmental abnormalities produced in these respective aneuploidies.
