The term "11p15" refers to a specific region on chromosome 11 in humans. This area is important because it contains genes that are involved in growth and development. Abnormalities in this region can lead to various genetic disorders, including Beckwith-Wiedemann syndrome and Silver-Russell syndrome. In the context of genetics, "11p15" is notable for its role in genomic imprinting, where certain genes are expressed in a parent-of-origin-specific manner. This means that the expression of these genes can differ depending on whether they are inherited from the mother or the father, influencing growth patterns and other biological processes.
