Recessive inheritance of the adult type of intestinal lactase deficiency.
In order to investigate the genetic control of the adult type of intestinal lactase deficiency, 61 families with 177 children over 6 years of age were investigated. The results strongly suggest that this deficiency is inherited as a simple Mendelian recessive trait.
