Genetic epidemiology and heritability of vitiligo in the Qassim region of Saudi Arabia.

Abstract

Genetic factors contribute to the evolution of vitiligo among Saudi families. Discouraging consanguineous marriage is a potential prevention measure. Genetic factors contribute to the evolution of vitiligo among tribal areas of the Saudi community probably through the high consanguinity rate. In that respect, family counseling can be attempted that would discourage consanguinity and combat probable interactive environmental and health factors.
