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 ...
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 ...
Patau syndrome. Patau syndrome is a syndrome caused by a chromosomal abnormality, in which some or all of the cells of the body contain extra genetic material from chromosome 13. The extra genetic material disrupts normal development, causing multiple and complex organ defects. This can occur either because each cell contains a full extra copy ...
1 in 74,000. Cat-eye syndrome (CES) or Schmid–Fraccaro syndrome is a rare condition caused by an abnormal extra chromosome, i.e. a small supernumerary marker chromosome. [2] This chromosome consists of the entire short arm and a small section of the long arm of chromosome 22. In consequence, individuals with the cat-eye syndrome have three ...
Full trisomy 9 is a rare and fatal chromosomal disorder caused by having three copies of chromosome number 9.It can be a viable condition if trisomy affects only part of the cells of the body or in cases of partial trisomy (trisomy 9p) in which cells have a normal set of two entire chromosomes 9 plus part of a third copy, usually of the short arm of the chromosome (arm p).
49, XXXXY syndrome. 5 alpha reductase 2 deficiency. 5-alpha-Oxoprolinase deficiency, rare (NIH) 5-Nucleotidase syndrome, rare (NIH) 5p minus syndrome. 5q- syndrome. 6 alpha mercaptopurine sensitivity, rare (NIH) 6-pyruvoyl-tetrahydropterin synthase deficiency, rare (NIH) 6-pyruvoyltetrahydropterin synthase deficiency.
The Dp(16)1Yu model (also referred to as Dp(16)1Yey) contains a partial duplication of the mouse chromosome 16 (MMU16). Unlike the Ts65Dn model, Dp(16)1Yu contains a duplication of only the parts of chromosome 16 that are homologous to human chromosome 21. This makes the Dp(16)1Yu model a more genetically accurate representation of Down Syndrome.
