imprintinghäiriöt
Imprintinghäiriöt refers to a group of rare genetic disorders that affect genomic imprinting. Genomic imprinting is an epigenetic phenomenon where certain genes are expressed in a parent-of-origin-specific manner. This means that either the allele inherited from the mother or the allele inherited from the father is silenced, while the other is active. Imprintinghäiriöt occur when this normal silencing mechanism is disrupted, leading to the inappropriate expression or silencing of specific genes.
The most common imprintinghäiriöt are Prader-Willi syndrome (PWS) and Angelman syndrome (AS). Both conditions are caused
Other, less common imprintinghäiriöt include Beckwith-Wiedemann syndrome and Silver-Russell syndrome. Beckwith-Wiedemann syndrome is characterized by overgrowth
