Leukocyte adhesion deficiency type II is a hereditary disorder of neutrophil
migration caused by mutations in the guanosine diphosphate-fucose transporter
gene (SLC35C1). In these patients, inability to generate key fucosylated
molecules including sialyl Lewis X leads to leukocytosis and recurrent
infections, in addition to short stature and developmental delay. We report two
brothers with short stature and developmental delay who are compound
heterozygotes for novel mutations in SLC35C1 resulting in partial in vivo defects
in fucosylation. Specifically, plasma glycoproteins including immunoglobulin G
demonstrated marked changes in glycoform distribution. While neutrophil rolling
on endothelial selectins was partially impeded, residual adhesion proved
sufficient to avoid leukocytosis or recurrent infection. These findings
demonstrate a surprising degree of immune redundancy in the face of substantial
alterations in adhesion molecule expression, and show that short stature and
developmental delay may be the sole presenting signs in this disorder.
