WebGenetic disorders occur when a mutation (a harmful change to a gene, also known as a pathogenic variant) affects your genes or when you have the wrong amount of genetic material. Genes are made of DNA (deoxyribonucleic acid), which contain instructions for cell functioning and the characteristics that make you unique. WebThe “epi” in epigenetics is derived from the Greek word meaning “above” or “over.”. Epigenetics is defined as the study of any process that alters gene activity without changing the DNA sequence. More simply, it is the study of gene expression — how external factors turn genes on and off, and up and down. The Human Genome Project ...
