Hypomelanosis of Ito
What are the causes?
It is now known that this pattern occurs when there are two populations of cells in the skin which vary because of a chromosome problem in one set of cells or a gene change. When skin cells are cultured, an abnormal chromosome pattern is found in one population of cells in about one third of affected individuals. The typical skin manifestations usually present in the first year of life with up to fifty-four per cent being noticeable at birth.
