Distal trisomy 10 is a rare chromosomal disorder that causes several physical defects and intellectual disability. [5] Humans, like all sexually reproducing species, have somatic cells that are in diploid [ 2N] state, meaning that N represent the number of chromosomes, and 2 the number of their copies. In humans, there are 23 chromosomes, but ...
Turner syndrome (TS), also known as 45,X, or 45,X0, is a genetic disorder in which a person's cells have only one X chromosome or are partially missing an X chromosome (sex chromosome monosomy).
The Pallister–Killian syndrome (PKS), also termed tetrasomy 12p mosaicism or the Pallister mosaic aneuploidy syndrome, is an extremely rare and severe genetic disorder. PKS is due to the presence of an extra and abnormal chromosome termed a small supernumerary marker chromosome (sSMC). sSMCs contain copies of genetic material from parts of virtually any other chromosome and, depending on the ...
The Ts65Dn mouse model was first introduced in 1993, [4] and more specifically resembles human trisomy 21 than the Ts16 model. In Ts65Dn, cells possess an extra copy of a segment of genes on chromosome 16 as well as a segment of genes on chromosome 17. From this model, various Down syndrome phenotypes are produced, including behavioral abnormalities and cognitive defects. [5]
Chromosome 10 is one of the 23 pairs of chromosomes in humans. People normally have two copies of this chromosome. Chromosome 10 spans about 134 million base pairs (the building material of DNA) and represents between 4 and 4.5 percent of the total DNA in cells .
17q12 microdeletion syndrome, also known as 17q12 deletion syndrome, is a rare chromosomal anomaly caused by the deletion of a small amount of material from a region in the long arm of chromosome 17. It is typified by deletion of the HNF1B gene, resulting in kidney abnormalities and renal cysts and diabetes syndrome. It also has neurocognitive effects, and has been implicated as a genetic ...

Marker chromosomes typically occur in addition to the standard 46 chromosomes, making it a partial trisomy or tetrasomy supernumerary chromosome. [4] A marker can be composed of inactive genetic material and have little or no effect, or it can carry active genes and cause genetic conditions such as iso (12p), which is associated with Pallister-Killian syndrome, and iso (18p), which is ...
