SUMMARY: In diploid organisms, autosomal genes are composed of two copies, or alleles, inherited from both parents at fertilization. For the vast majority of autosomal genes, expression occurs from both alleles simultaneously. ...

Genomic imprinting is defined as a gamete of origin-specific epigenetic modification of DNA leading to differential gene expression in the zygote. Several imprinted genes have been identified and some of them are associated ...

Genomic imprinting is a reversible phenomenon that affects the expression of genes depending on their parental origin, The best characterized human disorders resulting from an alteration Of the imprinting process are ...

DNA methylation is essential in X chromosome inactivation and genomic imprinting, maintaining repression of XIST in the active X chromosome and monoallelic repression of imprinted genes. Disruption of the DNA methyltransferase ...

Genomic imprinting alterations have been shown to be associated with assisted reproductive technologies (ARTs) in animals. At present, data obtained in humans are inconclusive; however, some epidemiological studies have ...

La teoría del Conflicto Genómico es parte de la biología evolutiva y actúa en los mamíferos a través del mecanismo de impronta genética, estos genes cumplen un rol central en el desarrollo fetal y del trofoblasto contribuyendo ...
