LAD II
Affected children are born after uneventful pregnancies with normal height and weight. No delay in the separation of the umbilical cord is observed. Affected individuals have the rare Bombay (hh) blood phenotype. Later in life, they show severe mental retardation, short stature, and a distinctive facial appearance. Infections are generally not life-threatening and are usually treated in an out-patient clinic. There is no pus formation at the site of infection. After the age of 3 years, the frequency of infections decreases and children no longer need prophylactic antibiotics [17]. The hallmark of LAD II syndrome is the deficiency in the expression of the sLeX antigen, the selectin ligand, on leukocytes. Neutrophilia (10,000-40,000/mm3) is a constant finding [18]. LAD II is also called congenital disorder of glycosylation type IIc (CDG IIc) syndrome.
