SIR, Monozygotic twin concordance rate for systemic lupus erythematosus (SLE) is 2457% with an overall population prevalence of 0.2% suggesting a dominant role of genetic predisposition to SLE susceptibility [1]. Genetic contribution to the incidence of SLE needs to be distinguished from that to the individual target organ injury within the disease.
