Founders are defined as individuals for whom there are no ancestral genealogical relationships in the Utah Population Database. Thus, they are the earliest generation in the database. FSIR: familial standardized incidence ratio. JIA subtypes: S = systemic JIA, R = RF + polyarticular JIA; P = RF negative polyarticular JIA, O = oligoarticular JIA, E = enthesitis related arthritis, Ps = psoriatic JIA, U = undifferentiated JIA. ANA: Anti nuclear antibody.
