Genomic Imprinting
BACKGROUND Genomic imprinting is the inheritance out of Mendelian borders. Many of inherited diseases and human development violates Mendelian law of inheritance, this way of inheriting is studied by epigenetics. AIM The aim of this review is to analyze current opinions and options regarding to this way of inheriting. RESULTS Epigenetics shows that gene expression undergoes changes more com...
متن کاملGenomic imprinting
Genomic imprinting is the epigenetic phenomenon by which certain genes are expressed in a parent-of-origin-specific manner. If the allele inherited from the father is imprinted, it is thereby silenced, and only the allele from the mother is expressed. If the allele from the mother is imprinted, then only the allele from the father is expressed. Forms of genomic imprinting have been demonstrated...
متن کاملGenomic imprinting
Genomic imprinting is a normal form of gene regulation that causes a subset of mammalian genes to be expressed from one of the two parental chromosomes. Some imprinted genes are expressed from the maternally inherited chromosomes and others from the paternally inherited chromosomes. This means that the maternal and paternal genomes are not functionally equivalent and is the reason why both a ma...

Studies of large imprinted clusters, such as the Gnas locus, have revealed much about the significance of DNA methylation, transcription and other factors in the establishment and maintenance of imprinted gene expression. However, the complexity of such loci can make manipulating them and interpreting the results challenging. We review here a distinct class of imprinted genes, which have arisen...
متن کاملGenomic imprinting and carcinogenesis.
The Mendelian inheritance is based on the fundamental rule in which mammalian genes are expressed equally from two homologous biparental alleles. Recently a small number of genes have been identified to show an exception to this rule in that homologous alleles can function differently in somatic cells depending on whether they come from the mother or the father. This intriguing biological pheno...
