  2. Distal trisomy 10q - Wikipedia

    en.wikipedia.org/wiki/Distal_trisomy_10q

    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 ...

  3. Trisomy - Wikipedia

    en.wikipedia.org/wiki/Trisomy

    The number of chromosomes in the cell where trisomy occurs is represented as, for example, 2n+1 if one chromosome shows trisomy, 2n+1+1 if two show trisomy, etc. "Full trisomy", also called "primary trisomy", means that an entire extra chromosome has been copied. "Partial trisomy" means that there is an extra copy of part of a chromosome.

    Oncology. Gestational trophoblastic disease ( GTD) is a term used for a group of pregnancy-related tumours. [1] These tumours are rare, and they appear when cells in the womb start to proliferate uncontrollably. The cells that form gestational trophoblastic tumours are called trophoblasts and come from tissue that grows to form the placenta ...

    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]

    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 ...

  7. Patau syndrome - Wikipedia

    en.wikipedia.org/wiki/Patau_syndrome

    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 ...

    en.wikipedia.org/wiki/17q12_microdeletion_syndrome

    17q12 microdeletion syndrome. 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.
