A genetic disease is a health issue that produces one or more deformity in the genes. It can be created through an alteration of a single gene or monogenic or multiple genes, otherwise known as polygenic, or through monosome irregularity. Even if the most common disorder is polygenic, the word is mainly applied when considering a disorder with a monogenic cause, whether in a gene or monosome.
The change can happen impulsively prior to embryonic growth, or it can be inborn from both parents who bring a damaged gene, or from one parent with the condition. Some of these disorders are generated by a variation on the X-connected and X monosome heritage. However, few conditions are inborn on the monosome.
