However, there was a trend towards higher MBL levels in cases with late AMD compared to participants with early AMD changes (1.0 (IQR 0.3–1.9) vs. 0.4 (IQR 0.1–1.4) μg/ml, p = 0.09), and MBL deficiency (<0.5 μg/ml) was encountered less frequently in the late AMD group (19 (35%) vs 31 (56%), p = 0.03). Here, MBL2 is linked to hyperinsulinemic hypoglycemia, familial, 4.
