PCSK9 and Schnyder corneal dystrophy: Total circulating leukocyte counts were significantly decreased in PCSK9 deficient SCD recipients (Pcsk9+/+, SCDbmt vs Pcsk9−/−, SCDbmt : 47.57 ± 2.99 vs 35.38 ± 3.24, p < 0.05), with neutrophils being the only subset of leukocytes significantly altered in PCSK9 deficient SCD recipients (Pcsk9+/+, SCDbmt vs Pcsk9−/−, SCDbmt : 13.98 ± 1.46 vs 8.61 ± 1.03, p < 0.005).
