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.
Partial aneuploidy The terms "partial monosomy" and "partial trisomy" are used to describe an imbalance of genetic material caused by loss or gain of part of a chromosome. In particular, these terms would be used in the situation of an unbalanced translocation , where an individual carries a derivative chromosome formed through the breakage and ...
"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.
Patau syndrome is the result of trisomy 13, meaning each cell in the body has three copies of chromosome 13 instead of the usual two. A small percentage of cases occur when only some of the body's cells have an extra copy; such cases are called mosaic trisomy 13.

Cri du chat syndrome is due to a partial deletion of the short arm of chromosome number 5, also called "5p monosomy" or "partial monosomy." Approximately 90% of cases result from a sporadic, or randomly occurring, de novo deletion.
Gonadal dysgenesis is classified as any congenital developmental disorder of the reproductive system [1] characterized by a progressive loss of primordial germ cells on the developing gonads of an embryo. [2] One type of gonadal dysgenesis is the development of functionless, fibrous tissue, termed streak gonads, instead of reproductive tissue. [3]
A karyotype of an individual with trisomy 21, showing three copies of chromosome 21. An abnormal number of chromosomes is known as aneuploidy, and occurs when an individual is either missing a chromosome from a pair (resulting in monosomy) or has more than two chromosomes of a pair ( trisomy, tetrasomy, etc.).
HLHS is also associated with several genetic syndromes, including trisomy 13 (Patau syndrome), trisomy 18 (Edwards syndrome), partial trisomy 9, Turner's syndrome (XO), Jacobsen syndrome (11q deletion syndrome), Holt-Oram syndrome, and Smith-Lemli-Opitz syndrome.
Isochromosome in which the arms are mirror copies of each other. An isochromosome is an unbalanced structural abnormality in which the arms of the chromosome are mirror images of each other. [1] The chromosome consists of two copies of either the long (q) arm or the short (p) arm because isochromosome formation is equivalent to a simultaneous ...
