As a consequence of congenital genetic mutations, approximately 65 percent of people experience some sort of health issue. A known single-gene problem affects about 1 in 50 persons, whereas a chromosomal issue affects about 1 in 263 people. There are around 600 ailments that can be treated. There are about 6,000 documented genetic illnesses, and new genetic abnormalities are documented in the medical literature on a regular basis. Only a small percentage of diseases are inherited from the Y chromosome or mitochondrial DNA. Certain illnesses have X-linked inheritance and are associated with mutations on the X chromosome. It is sometimes referred to as a hereditary disease whenever the genetic abnormality is inherited through one or both parents. The mutation that causes the disorder can happen suddenly before embryonic development (a de novo mutation), or it could be acquired from two parents who've been carriers of a faulty gene (autosomal recessive inheritance), or through a parent who already has the disorder (autosomal dominant inheritance). Although polygenic illnesses are the most frequent, the term is typically applied to conditions that have a single genetic origin, such as a mutation in a gene or chromosome. A chromosomal anomaly or a mutation in a single gene (monogenic) or multiple genes (polygenic) could be the reason for the same. Genetic Disease:- A genetic disorder is a medical condition caused by one or even more genetic defects.
