Familial systemic lupus erythematosus characterized by digital ischemia.
We describe a family in which 3 members each developed systemic lupus erythematosus complicated by ischemic vasculopathy. The calendar years and patient ages of disease onset and the clinical courses were remarkably similar for all 3 patients, although their genotypes were not. The potential contributions of heredity and environment to the concordance of disease expression in this family are discussed.
