The chances of any child to develop symptoms of vitiligo are .5-2%. We observe that 20-38 % of the patients have first and second degree relatives who also have the disease. As for the genetic data, it indicates a multifactorial, gene- related heredity which doesn’t follow Mendell’s laws and is the result of an anomaly which distorts the composition and distribution of melanin, or changes the melanosome’s biology (transfer- biogenesis- melanization). The incidence of vitiligo among first degree relatives reported in a study of Caucasian, Indian-Pakistani and Hispanic populations is 7.1%, 6.1% and 4.8% respectively. Therefore, if heredity does exist, there is greater possibility for a Caucasian child to develop vitiligo.
