Information on L\u00f6fgren's syndrome was available for a subset diagnosed at Karolinska University Hospital (Stockholm, Sweden). General population controls were matched to cases (10:1). Relatives of cases and controls were identified from the Swedish Multi-Generation Register and ascertained for sarcoidosis in the National Patient Register. We estimated familial relative risks for sarcoidosis using conditional logistic regression and heritability using biometric models.<\/jats:p><jats:p>Having at least one first-degree relative with sarcoidosis was associated with a 3.7-fold increase in the risk of sarcoidosis (95% CI 3.4\u22124.1). The relative risk increased in those with two or more relatives (relative risk 4.7) and in L\u00f6fgren's syndrome (relative risk 4.1). The heritability was 39% (95% CI 12\u221265%).<\/jats:p><jats:p>This large investigation showed that having a relative with sarcoidosis is a very strong risk factor for the disease.
