Epimutations are abnormal epigenetic changes that alter gene regulation without necessarily changing the DNA sequence. Learn about their types, mechanisms, causes, DNA methylation, histone modifications, disease associations, epigenetic testing, inheritance, and therapeutic significance.

Imprinting control regions are specialized genomic regions that regulate parent-of-origin-specific gene expression. Explore DNA methylation, differentially methylated regions, histone modifications, chromatin remodeling, non-coding RNA, germ-cell imprinting, epigenetic reprogramming, imprinting disorders, and their role in development.

Paternal germline differentially methylated regions (paternal gDMRs) are genomic regions that acquire parent-specific patterns of DNA methylation during the development…

Maternal germline DMRs are established during oocyte development through regulated DNA methylation and contribute to genomic imprinting, maternal epigenetics, and early embryonic development.

DNA methylation during oogenesis establishes important epigenetic patterns in developing oocytes and contributes to maternal germline DMRs, genomic imprinting, oocyte development, and early embryonic regulation.

The oocyte methylome is the genome-wide DNA methylation landscape established during oogenesis and involved in maternal epigenetic regulation, genomic imprinting, fertility, and embryonic development.

Oocyte DNA methylation is an important epigenetic process established during oogenesis that contributes to genomic imprinting, maternal epigenetic regulation, fertility, and early embryonic development.

DMRs in oocytes are important regions of differential DNA methylation associated with oogenesis, genomic imprinting, epigenetic regulation, fertility, and early embryonic development.

DMRs in sperm are important regions of differential DNA methylation associated with sperm development, genomic imprinting, epigenetic regulation, fertility, and early embryonic development.

Maternal germline differentially methylated regions are established during oocyte development and help regulate genomic imprinting, parent-of-origin gene expression, and early embryonic development.

Germline differentially methylated regions establish parent-specific DNA methylation patterns during sperm and oocyte development and help regulate genomic imprinting and early embryonic development.

DNA methylation at imprinting control regions is a key mechanism of genomic imprinting. Learn how methylation is established, maintained, and reprogrammed and how it regulates parent-of-origin gene expression and development.

Differentially methylated regions are genomic regions with distinct DNA methylation patterns that can regulate gene expression and genomic imprinting. Explore imprinting-associated DMRs, DNA methylation, germ-cell reprogramming, parent-of-origin effects, epimutations, imprinting disorders, development, and epigenetic inheritance.

Genomic imprinting is an epigenetic mechanism that causes certain genes to be expressed according to their parental origin. Explore DNA methylation, imprinting control regions, histone modifications, non-coding RNA, germ-cell reprogramming, parent-of-origin effects, imprinting disorders, and the relationship between genomic imprinting and epigenetic inheritance.

Germ-cell epigenetic memory refers to persistent epigenetic information associated with sperm or oocytes that may influence gene regulation and development. Explore DNA methylation, histone modifications, non-coding RNA, genomic imprinting, germ-cell reprogramming, environmental influences, and the evidence for inheritance across generations.
