Epigenomics is an emerging branch of genomics that explores heritable changes in gene activity that occur without altering the underlying DNA sequence. These changes, mediated through DNA methylation, histone modifications, chromatin remodeling, and non-coding RNAs, play critical roles in gene regulation, development, cellular differentiation, and disease progression.

With the rapid advancement of next-generation sequencing (NGS) technologies, epigenomic studies generate massive datasets that require sophisticated computational analysis to uncover biologically meaningful insights. Successful epigenomic research depends on the careful integration of experimental design and bioinformatics analysis, ensuring that subtle but biologically significant epigenetic changes are accurately identified and interpreted.
