8q211

8q211 is a designation used in the International System for Human Cytogenetic Nomenclature (ISCN) to identify a specific chromosomal aberration. The "8" refers to chromosome 8, the "q" indicates the long arm of the chromosome, and "211" specifies the band on the long arm. This particular band is located on the long arm of chromosome 8, between bands 8q21 and 8q22. The 8q211 band is a region of interest in cytogenetics due to its association with various genetic disorders and syndromes. One notable example is the 8q21.1 deletion syndrome, which is characterized by a deletion of genetic material in this region. This syndrome can lead to a range of symptoms, including intellectual disability, developmental delays, and specific physical features. The 8q211 band is also associated with other genetic conditions, such as certain types of cancer and developmental abnormalities. Advances in genetic testing and molecular biology have allowed for a better understanding of the genetic material within this band and its role in human health and disease.
