4p16.3 (chromosomal location)

4p16.3 refers to a specific region on the short arm (p) of chromosome 4, at position 16.3. Chromosomes are structures within our cells that carry genetic information. The "4" indicates chromosome 4, "p" indicates the short arm, and "16.3" specifies a precise sub-region within that arm. This area contains genes important for development and function. Alterations in 4p16.3, such as deletions or duplications, can be associated with certain genetic syndromes or health conditions, making its study valuable in genetics and medicine.
