Chromosome 18 banding
WebThe banding pattern can distinguish chromosomal abnormalities or structural rearrangements, such as translocations, deletions, insertions, and inversions. G-banding has been divided into regions, bands, and subbands. Fig. 13.4 shows a typical diagram of the bands of the human X chromosome. WebThe results of the mBAND indicated that the derivative chromosome 18 had a deletion from band q21.3 to the terminal region that stained dark blue, pink, and orange on the normal 18 and a duplication of the region from 18p11.3 to 18pter that stained light blue and yellow in color. The deleted region was larger than the region defined by ...

WebDescription. Distal 18q deletion syndrome is a chromosomal condition that occurs when a piece of the long (q) arm of chromosome 18 is missing. The term "distal" means that the missing piece occurs near one end of the chromosome. Distal 18q deletion syndrome can lead to a wide variety of signs and symptoms among affected individuals.
