Is Henoch-Schonlein purpura inherited ?
Can Henoch-Schonlein purpura be inherited? The cause of Henoch-Schonlein purpura is currently unknown.  Some evidence suggests that genetic predisposition may contribute to the development of this disease in some cases.  Only a few families with multiple relatives affected by HSP have been reported in the medical literature.  The association between particular genes and a slight increase in the chance of developing HSP has not been proven.
