Distal trisomy 10 is a rare chromosomal disorder that causes several physical defects and intellectual disability. 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.

15q overgrowth syndrome. Other names. 15q26 overgrowth syndrome. 15q overgrowth syndrome is a rare partial autosomal trisomy / tetrasomy syndrome. [1] The condition was first identified in a 2009 report. [2]
Cri du chat syndrome. Cri du chat syndrome is a rare genetic disorder due to a partial chromosome deletion on chromosome 5. [1] Its name is a French term ("cat-cry" or "call of the cat") referring to the characteristic cat-like cry of affected children (sound sample [1] ). [2] It was first described by Jérôme Lejeune in 1963. [3]
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 ...
Full. Full tetrasomy of an individual occurs due to non-disjunction when the cells are dividing ( meiosis I or II) to form egg and sperm cells ( gametogenesis ). This can result in extra chromosomes in a sperm or egg cell. After fertilization, the resulting fetus has 48 chromosomes instead of the typical 46.
"Partial trisomy" means that there is an extra copy of part of a chromosome. "Secondary trisomy" - the extra chromosome has quadruplicated arms (the arms are identical; it is an "isochromosome"). "Tertiary trisomy" - the extra chromosome is made up of copies of arms from two other chromosomes.
Specialty. Medical genetics. Distal 18q- is a genetic condition caused by a deletion of genetic material within one of the two copies of chromosome 18. [1] The deletion involves the distal section of 18q and typically extends to the tip of the long arm of chromosome 18. [2]
13q deletion syndrome is a rare genetic disease caused by the deletion of some or all of the large arm of human chromosome 13. Depending upon the size and location of the deletion on chromosome 13, the physical and mental manifestations will vary. It has the potential to cause intellectual disability and congenital malformations that affect a ...
Trisomy 13 (Patau syndrome), trisomy 18 (Edwards syndrome) Triploid syndrome, also called triploidy, is a chromosomal disorder in which a fetus has three copies of every chromosome instead of the normal two. If this occurs in only some cells, it is called mosaic triploidy and is less severe. Most embryos with triploidy miscarry early in ...
