control relatives.A ratio of s/q approached1/q with Penrose' s method.Heritability of SLE was78.8%?4.45%in the first-degree relatives,58.8%?10.9%in the second-degree relatives,and39.2%?32.0%in the third-degree relatives.The weighted mean heritability was75.2%?4.12%.Conclusions SLE has characteristics of polygenic disease.Genetic factor might play an important role in the liability of SLE.
