Laboratory testing confirmed central precocious puberty (CPP) with elevated luteinizing hormone (LH) at 5.60 mUI/mL (reference value (RV): 0.02-0.3 mUI/mL), follicle-stimulating hormone (FSH) at 4.45 mUI/mL (RV: 0.26-3.0 mUI/mL) and testosterone of 1163.90 ng/dL (RV: <2.5-10 ng/dL). Here, PLOD1 is linked to central precocious puberty.
