A microsatellite repeat polymorphism was identified in the 3' flanking region of the human ETS1 gene. Sequencing revealed two CA repeat segments in close proximity. Seven different alleles comprising various combinations of CA repeat units were identified in a healthy control population. Because ETS1 plays a role in lymphocyte development and function, apoptosis, and inflammation, we examined whether any of these polymorphisms were associated with a systemic inflammatory condition, systemic lupus erythematosus (SLE). Inheritance of this disease is polygenic and a recent genome-wide screen for SLE susceptibility loci revealed linkage with chromosome 11q14-23, the region in which the ETS1 gene lies. This region has also been identified as a general autoimmune susceptibility region. None of the seven distinct ETS1 alleles appeared statistically more frequently in SLE patients than controls, however, two alleles were associated with particular clinical manifestations. Allele 1 is associated with discoid lesions and allele 7 is associated with vasculitis. While this polymorphism does not directly affect the coding region of ETS1, it may be a marker for overexpression of a particular isoform or inheritance of another polymorphism which does affect function. These data suggest that ETS1 may be involved in the phenotypic expression of Systemic lupus erythematosus. (C) 2000 Wiley-Liss, Inc.
