X inactivation turns off entire chromosomes, whereas imprinting turns off only specific genes. How do these processes work, and why do they often produce similar results? Upon examining their ...

But what happens when one of these genes has been "turned off", or imprinted, and the remaining gene is defective? Angelman syndrome (Figure 1) is a disorder of the nervous system characterized by ...

Not only are alleles inherited from a mouse’s mom or dad expressed in unequal proportions in various cells in the brain and adrenal system—a phenomenon called genomic imprinting—but expressing the ...

In a latest research, scientists from Jiangsu University have developed an advanced method for the specific identification of ...

Mammalian reproduction involves genomic imprinting, a process in which epigenetic modifications restrict the expression of certain genes to a single parental allele. The genes that are silenced or ...
