Each chromosome is divided into two sections (arms) based on the location of a narrowing (constriction) called the centromere. By convention, the shorter arm is called p, and the longer arm is called q. The chromosome arm is the second part of the gene’s address. For example, 5q is the long arm of chromosome 5, and Xp is the short arm of the X chromosome.
Other forms of Turner include mosaicism for X chromosome monosomy (eg, 45,X/46,XX) or 45,X/46,XY mosaic with or without a partial deletion of the Y chromosome. The remaining patients have a structural abnormality of the second X chromosome (eg, an isochromosome of the long arm of X or a deletion involving the short arm of one X). Deletions involving the distal portion of the short arm of the Y chromosome.
Other abnormal structural changes in the chromosome are consequences of some kind of chromosomal breakage, with either the loss or rearrangement of genetic material. translocation involves the transfer of a segment of one chromosome to another. inversion refers to a change in the sequence of genes along the chromosome, which occurs when there are two breaks in a chromosome and the segment between the breaks is reversed and reattached to the wrong ends. deletion occurs when a portion of a chromosome is lost. An example of this type of chromosomal abnormality is cri du chat syndrome, a deletion in the short arm of chromosome.
