People who have ancestry from Sub-Saharan Africa, Asia, or Latin America are more likely to develop a<unk> . Among ethnic Chinese in Asia, the<unk>  is the most common skin condition. In the United States,<unk> s are more common in African Americans and Hispanic Americans than whites. Those who have a family history of<unk> s are also susceptible since about 1/3 of people who get<unk> s have a first-degree blood relative (mother, father, sister, brother, or child) who also gets<unk> s. This family trait is most common in people of African and/or Asian descent. Development of<unk> s among twins also lends credibility to existence of a genetic susceptibility to develop<unk> s. Marneros et al. (1) reported four sets of identical twins with<unk> s; Ramakrishnan et al. also described a pair of twins who developed<unk> s at the same time after vaccination. Case series have reported clinically severe forms of<unk> s in individuals with a positive family history and black African ethnic origin.
