Somatic mutation If a somatic mutation occurs in a single cell in developing somatic tissue, that cell is the progenitor of a population of identical mutant cells, all of which have descended from the cell that mutated. These types of mutations are considered germline mutations.
The somatic cells that have differentiated can become adult neurons in the nervous system, blood cells in the cardiovascular system, liver cells in the digestive system, or any of the many other types of cells found throughout the body.

A mutation producing an allele for white petals that arose originally in somatic tissue but eventually became part of germinal tissue and could be transmitted through seeds. In people with chloasma, the majority of cases will resolve spontaneously within a year.

As mentioned above, chronic inflammation in the skin can induce DNA mutations in skin cells, which greatly increases the risk of developing squamous cell carcinoma. It can also cause irritation of the skin, so is a good idea to test a tiny amount of cream on a small, unaffected area first.
This form of the disease is the result of abnormalities in collagen a type of connective tissue and laminin a protein found in the basement membrane which helps to hold cells and tissues together. One is a chemical peel, where a chemical solution is applied to the skin causing the upper layers of dead skin to peel off.
The long-term skin inflammation caused by dystrophic epidermolysis bullosa is problematic, as it can damage the DNA within the skin cells.
