Description : Individuals with Lan(-) blood group lack the Lan antigen on their red blood cells.
These individuals may have anti-Lan antibodies in their serum, which can cause transfusion
reactions or hemolytic disease of the fetus or newborn. The Lan(-) blood group is
only clinically significant in transfusion settings or during pregnancy; otherwise
Lan(-) individuals have no clinical features (summary by Helias et al., 2012).;
