Pre-implantation genetic diagnosis (PGD) is a method aimed at eliminating embryos created by in vitro fertilization (IVF) that have abnormal chromosomes or carry a serious genetic disease before pregnancy begins. Genetic diagnosis of preimplantation (PGD) refers specifically to when one or even both of the genetic parents have a known genetic abnormality, and testing is conducted at an early level to determine if it does not carry a genetic anomaly.

A hereditary disease is any condition caused by abnormality in a person’s genetic makeup/ genome. It can range from major to minor abnormality- from a gross abnormality involving subtraction/ addition of a whole chromosome/ set of chromosomes to a distinct mutation in one base of a particular gene’s DNA.
Some hereditary diseases are passed on from parents, whereas others result from acquired mutations/ changes in preexisting group of genes or one preexisting gene.
In most cases, mutations are caused by environmental exposure. In other cases, however, they occur randomly.
