CD177 and Decreased total neutrophil count: The neutrophil surface lipoprotein CD177 (fold change [FC] = 45.1), first described in neonatal neutropenia (Lalezari et al, 1971) and the mast cell protein MCEMP1 (FC = 11.4), involved in mast cell maturation, were identified as the most strongly differential expressed genes in both cohorts (Table S3).
