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...
متن کاملMechanisms of genomic imprinting.
Imprinted genes represent a curious defiance of normal Mendelian genetics. Mammals inherit two complete sets of chromosomes, one from the mother and one from the father, and most autosomal genes will be expressed from both the maternal and the paternal alleles. Imprinted genes, however, are expressed from only one chromosome, in a parent-of-origin-dependent manner. Because silent and active pro...
متن کاملGenomic Imprinting Is Implicated in the Psychology of Music.
Why do people sing to babies? Human infants are relatively altricial and need their parents' attention to survive. Infant-directed song may constitute a signal of that attention. In Prader-Willi syndrome (PWS), a rare disorder of genomic imprinting, genes from chromosome 15q11-q13 that are typically paternally expressed are unexpressed, which results in exaggeration of traits that reduce offspr...
